Wiz quiz for Double or Nothing

If you have wiz, run a few hands in the quiz with Stars double or nothing format. There are some interesting spots that I think that most, including me, would have a hard time folding. Ex.:

Blinds: 100/200/25
UTG: 411 - Tight
UTG+1: 763
UTG+2: 417
UTG+3: 2219
Hero: 7870
BN: 464 - Loose
SB: 724 - Average
BB: 632 - Very Tight

Action:
UTG - Push
Fold
Fold
Fold
Hero: AJo - Wiz says fold and no hand is a call even if they are shoving very loose.

Here's another one:
Blinds 300/600/50
Hero: 6158 - AKo
UTG+1: 3310
CO: 905
BN: 1208
SB: 809
BB: 1110
Wiz says that you can not shove any hand in this spot. Even if you change the ranges of the players it is a fold.

So what did we learn here?

Guess the double or nothing format is very similar to a satellite in that all that matters is getting ITM with nothing extra for winning. This leads to a very severe ICM effect on or close to the bubble - so the AK hand makes sense to me.

I still can't work out the AJo hand however, maybe something to do with the chance of getting called by either Button, SB or BB?

This is what I think:-

I think the AJo hand is a fold because there are so many short stacks left in. Hero has 7870 chips remaining, and is pretty much guaranteed to get in the money, even if he folds every hand.
Apart from UTG+3, nobody even has 4xBB remaining, and there are antes too. Only three more players need to get knocked out, so I guess it is better to let them battle it out among themselves.
You wouldn't want to call a push here, have the SB push too, and risk over 700 chips when you don't need to. I think it is better if just another short stack calls the push. Even if you call the UTG push, nobody else calls, and you win, it doesn't really make much difference to Hero's stack.

With the AKo hand, only one more player needs to get knocked out before you get in the money. You wouldn't want to push here, get called by UTG+1, and lose over half your stack.

Given the payout structure the most EV+ move is to sit out and do something else
