Something odd about neural parasite

[Strilanc]

I was playing impossible scenarios and made it to the last level. Figuring I would neural parasite my way to victory I made infestors only to discover something very odd:
The AI attacks any unit you ORDER the spell on, whether or not you cast it!

Needless to say, that made the level super easy. I just order-stop order-stopped my way to victory from a mile away.

This brings up the question: how else can this be abused? Does it work in melee games? Are there other custom maps with this flaw?

If its an aggro bug then you won't be able to use in in melee games unless your enemy likes to look away from the screen a lot.
