For each Integer VS Pick each Integer

[Avator]

I think we all know about the For each Integer command in WC3, but now there's another command in SC2 GUI called Pick each Integer.

Does anybody know why the Pick each Integer command has been added if it's just the same except it's missed 2 input slots? Or is there something more about this function? For as far as I know it should do the exact same.



EDIT: I shouldve actually called this topic "Dubble commands", because I see a few mroe commands that are pretty much in dubble unless somebody can explain the difference between them. I'll post which commands those are once I checked them all.
