I'm inclined to agree with you. Airports tending to be full of hyper-aware pilots who are communicating on the same radio frequencies as you shouldn't really be considered a safety margin, but it can still prevent accidents sometimes.
Incidentally, Aviation Herald reports[1] that "AC-759 had already overflown taxiway C by about 0.25nm when ATC instructed the aircraft to go around" and further that "it is estimated that AC-759 overflew the first two aircraft by 100 feet".
100 feet isn't much, and I imagine this was utterly terrifying for the pilots lined up on the taxiway, but 0.25nm past the beginning of taxiway C is basically touchdown point on the runway (had they been lined up with it), and they were still 100 feet above the ground. That indicates pretty strongly that the pilot of AC-759 had noticed their mistake and was taking evasive action already, before ATC instructed them to go around.
