Possible they initiated a very late attempt to GA?
If so it would be a very serious mistake and frankly I doubt it.
Once on the ground and by the time you realize something is not working it it is usually too late to do G/A, you would have to reset flaps, make sure all flight controls/TH are in stowed position, etc, it takes time while you are eating precious runway. It is much better to run off the runway at say 80 kts than attempt a late G/A and run off the runway at say 130 kts. Rule of a thumb in aviation is to reduce your energy once on the ground, there were many well publicized accidents (mostly in GA) when pilots attempted ill thought late go-around with horrific results. For example in 2008 there were an accident with a business jet attempting such late go-around and it is very educational what NTSB said in its final report:
“If the captain had continued the landing and accepted the possibility of overrunning the runway instead of attempting to execute a go-around late in the landing roll, the accident most likely would have been prevented or the severity reduced because the airplane would have come to rest within the runway safety area,” according to the findings.
