Combining and modifying RA/MA/Fear Clarification

Here, I saw the ruling that when combining Melee Attacks/Ranged Attacks/Fear Effects, each attack being combined must come from a different card in the unit. When using a combined attack, Interrupts that are not additional attacks being combined with it may still be used even if they're on the same card as one of the attacks being combined, correct?

For instance, let's say I have Moshi Ikako at a battlefield with Steal the Candle's Flame attached to her, and Higher Ground is in play (played by me). Can I declare her Ranged 1(+1) Attack, combine it with the spell's Ranged 0(+1) Attack, and then use the spell's Interrupt to give the total Ranged Attack +2 Strength (even though it's on the same card as one of the combining Ranged Attacks), for a total Ranged 5 Attack?

The rules for combining don't affect at all other types of Interrupts that modify the strength. It is perfectly legal to use Interrupts that increase the strength of the effect even if they come from the same card that is producing the RA or combining with it. There's no objection to using Steal the Candle's Flame Battle ability and increase the resulting RA with its own Interrupt ability.
