I don't think this is a standard pushing situation per se, but I can see reasons for it.

Big stack is probably gonna be open pushing about every hand so this may be the only time hero has a chance to pick up blinds without contest for a while. Villain is probably gonna put hero on a pretty narrow range of hands pushing from UTG and will likely fold most hands.

All of the other stacks are smaller than hero's with the largest immediately to his left (putting him on the narrowest range), but none are desperate enough to call with garbage.

I think A8 is getting very close to the bottom of his push range here, but given the situation, I like the play.
