I have Hisao defending a province against an attacking personality. I have Bayushi Tsimaru (Experienced) at home.
I play Knowledge, paying the gold cost, and targeting Hisao and the attacking personality.
Can I react with Tsimaru twice (once per each movement), effectively keeping Hisao and the Attacking Personality at the battlefield?
I have Hisao defending a province against a bowed army of two attacking units. I have Bayushi Tsimaru (Experienced) at home.
My opponent plays Ordered Retreat. He attempts to target and move both his personalities home.
Can I react with Tsimaru twice (once per each movement), effectively keeping both bowed personalities at the battlefield?
In both cases, assume I have not yet used Tsimaru's reaction.

Yes to both questions. Although a player can not use the same Reaction twice to a single triggering occurrence from the same copy of a card (see Timing), each separate movement is a distinct triggering occurrence in order to take Tsimaru's Reaction.

Regarding this ruling: http://www.alderac.com/forum/viewtopic.php?f=59&t=69051
Tsimaru negates a unit's movement twice in a turn, specifically referring to the unit itself rather than the action, so playing the action Ordered Retreat isn't triggering the movement, but rather the effect of the card. Wouldn't therefore Tsimaru be able to negate the movement of both units, assuming his ability hasn't been used yet? It seems to be intuitive, because if Tsimaru was triggered by the Ordered Retreat itself, his ability would negate all movement of Ordered Retreat, rather than only preventing two units from moving. Unless I'm missing something here, of course.

Not exactly. Bayushi Tsimaru (Experienced)'s Reaction refers to, and is triggered by, any one movement (of any one unit); see also Move and Unit in the glossary. It doesn't matter whether that movement comes from an action, a trait or a rule: Tsimaru's action's effect negates it. It doesn't matter whether more than one unit are moving simultaneously: Tsimaru's ability is used during one specific round of Reactions played before the movement of one of those units (see Timing).

Sorry, I don't understand what you mean...

Yes, that is exactly what I said at first. Please accept my excuses if my previous answer was ambiguous.
