Quick Question - Leave region event includes dying/removed units?

Does the leave region event trigger off of units dying/being removed?

I know the enter region event includes created units. I'm wondering if the opposite is true.

I'm hoping to remove them from a unit group when they die/are removed.

(Obviously I can do a unit death event, [but not a unit removal - or does unit removal trigger the unit death event?,] but I'm still curious if death triggers the leave region event.)

No, the leave region event doesn't trigger, both on dying and removed units.
No, the unit death event doesn't trigger when unit is removed.

Remove unit trigger no events at all.

You cant detect this call.
