Question related to mission Bats Bunker

 

In the description it is said that : "The entrance is placed at top left cell and there's always a bat right there.".

By definition the Alpha Bat is the strongest bat of the bunker => is a bat. Can the alpha bat position be at the entrance of the bunker ? If that the case, I think a case should be add to the checker (see attached picture).
