This sort of thing happens with dq timeout it isn't a glitch. His knee was most likely on the ground for 20 frames or more and it touched the ground again within the 40 frame dqt resulting in dq. Watch the reply pause in 40 frame intervals and check for yourself.

As a side note, I've never seen a gm force someone to send back from glitches anyway (prime examples would be grab collision glitch in abd.)
