*Groan* again the thing hasn't been called a roll bar for decades, and sure it may accidentally offer some protection to occupants, but don't bet on it.The hard top is not there to protect you (and soft top) in case of a roll over. The roll bars are there to protect the occupants of the vehicle.
I would advise anyone wanting to know more about the sports bar to look up reliable information about it.
This is from a quick search online
Jeep makes it a point to refer to it as a sports bar instead of roll cage, establishing bar isn’t designed for rolling over
