ATC shove on $0.50 45man Bubble

I have been active, stealing fairly wide in the SB, stats on the BB are 15/13 over 48 hands.

Q1. Am I correct that the sit out player in MP2 means that this is a shove with ATC and the BB can only call QQ+

I have checked the hand in SNGwiz and it is a push, also Holdem Resources gives the following ranges.

Q2. I am confused by the BB being able to call 88+. Does this mean pairs only as no AQs+ or AKo is quoted?
