Until the End of Turn confusion

I was trying to explain chi death and got myself confused. I haven't been able to find anything satisfactory for an answer.

If I give a chi penalty (sufficient to kill) to a hero personality, and they react with strength of the bamboo it seems that there are now two effects that last until the end of the turn. Does the active player choose which 'until the end of turn' ends first, or do they dissolve seperately?

More directly, in the above example, if I am the active player, at the end of the turn can I choose for the negation effect from Strength of the Bamboo to end before the temporary chi penalty does, thereby killing the hero personality?

The effects end simultaneously; there is no window of time when the "chi death" effect applies but Strength of the Bamboo doesn't.

Note that while triggered traits, delayed effects, ICE's and Reactions triggered by an effect or other trigger - or by simultaneous effects or triggers - are applied or resolved separately, not simultaneously, other sets of effects can resolve simultaneously.

Follow up to this ruling.

The rules define effects as... "An effect is anything, other than a cost, that changes the stats, traits, abilities, restrictions, or capabilities of a card, a player, a game entity (such as Provinces), or the game state."

Then under Timing Sequence the rules say... "Two Reactions, triggered traits, or other triggered occurrences (e.g., Honor loss after a dishonorable Personality dies; delayed effects) will never begin at the same time."

Then under Prevention of Effects the rule say... If a continuous effect or a current ongoing effect that has been prevented is still in effect when the prevention effect ends (for example, when the duration of an ongoing prevention runs out, or a card with a continuous prevention effect leaves play), the prevented effect re-asserts itself.

Wouldn't the ending of an effect be a "triggered occurance" (triggered by the game state advancing to the next procedural Turn/Phase) for purposes of the timing rules, and therefore two things that both last "until end of turn" be subject to "active player chooses"?

In short, what is the difference between the game state change created by the begining of an ongoing effect and it's ending? Nothing in the rules for ongoing effects, says that the game state change enduced by the ending of such an effect is imune to the timing rules.

Also under "Duration and Scope of Prevention Effects" there is a typo in the following sentance(my proposed correction in brackets)... A continuous effect from a non-triggered trait that prevents a type of occurrence lasts while its source card is in play. Each separate application of prevention from a "parent" [on]going or continuous effect is a “child” indefinite conditional effect.

The game state changes caused by the simultaneous ending of ongoing effects happen simultaneously.

Triggered traits, delayed effects, ICE, Reactions, etc, which would be triggered by the multiple simultaneous effects resolve according to the normal timing sequence.

In regard to the response from AkodoGilador.

"The game state changes caused by the simultaneous ending of ongoing effects happen simultaneously."

Where is that in the comp rules? And how does that jive with the Timing Rules...

"Two Reactions, triggered traits, or other triggered occurrences (e.g., Honor loss after a dishonorable Personality dies; delayed effects) will NEVER begin at the same time." (emphasis added)

The two quoted statements are mutually exclusive. So which is correct?

An effect expiring is not a Reaction, triggered trait, or triggered occurrence. Yes, I do see how one could interpret "triggered occurrences" should include effects expiring at the end of their stated duration. But triggers refer to things starting, not stopping (which I think is consistent with peoples' normal understanding of the word). Still, a little clean-up of the wiki would not go awry.
