"Exit Animations" triggered by timeline

I've encountered this problem, too. It's a problem with object animations and the end of a layer timeline-- but it doesn't matter whether it's the base layer or another layer.

Here's how it SHOULD be:

• Setting an object entrance animation indicates that if the object ever goes from a Hidden state to a non-Hidden state, then it appears via the indicated animation.
• Setting an object exit animation indicates that if the object ever goes from a non-Hidden state to a Hidden state, then it disappears via the indicated animation.

How it ACTUALLY works is similar to the above, PLUS:

• having an entrance animation overrides "Show Always"
• having an exit animation overrides "Show Always" and "Show Until End"

("Show Always" and "Show Until End" can be found by right-clicking an object's timeline).

I believe Phil when he says this is by design; I suspected the override was put there deliberately. I'd be curious to know why it was put there. It saves someone a step if they wanted stuff to fade out at the end of the timeline, but it dramatically increases the number of steps required when anyone wants to bypass the override.
