Video of Ravens Coach John Harbaugh Squatting 400-Pounds

It's a gay bar

It's a safety bar (looks to be modified). Good bar for athletes as it forces better positioning and really helps with load distribution.

That said, 405 under a safety bar is a completely different animal than 405 under a straight BB.

While eating a po-boy

That is absolutely a full 90 degree squat, and 95% saying it isn't deep enough on Twitter and here likely go higher than that. The only thing that doesn't count is he is pulling up with his hands on bars. Obviously can't use arms in squat, but the deepness is plenty good enough.

There's always some loser on squat videos that says "not deep enough", yet could prob max out at 255 at the butt depth Harbaugh is doing here, just not using arms.
