Two things for me here.
I suspect such a spontaneous and brutal retaliation will have come before the referee has a chance to reverse the first infringement.
In any event, the situation takes it beyond a straight reversal and is not relevant to the game.
However I can perhaps envisage a situation where the referee may indicate, once the melee has died down, he might have reversed the initial infringement but due to the escalation it is the most serous infringement that drives the final decision. In practical terms it is not technically a reversal of a reversal!
