Norris didn't get any advantage. On the contrary, he had to abandon the start and start again later than everyone around him.

This is not an excuse to ignore a case where there is clear visual evidence of a car moving before lights out. His movement could have spooked other cars into moving which could have ruined their starts. You can see people making jump starts in response to other jump starts often in athletics especially in short races like 100m, etc.

Also it was not a case where he drifted just a few mm. He moved nearly half a wheel rotation in that false start and somehow the transponder either didn't pick it or found it to be within limits. Either the way the transponder sensitivity has to be improved.
