Bumper zone contact is expected. Bumpers are variable in their distance from the floor by up to 3 inches, so it's easy for a 'natural' wedge to form with the bumper apexes. There's also probably a 50lb difference between those two robots. These are the facts, and both robots are 100% legal given the probable variables at play.

The subjectivity is how quickly the flip happens, and if either driver really had time to back off. Even my driver, with the best reflexes we've ever had on my team, would probably have not prevented that flip. Thus it falls to benefit of the doubt to both teams there. It happened too quickly for a foul to be called. Of course, this is IMO.
