I don't think the board are backtracking at all - think they are giving these guys a second chance, which they would be well advised to take.
The neddish behaviour is completely out of order, personally, I think Graeme Rae is being fairly magnanimous here.
Going to a game & vandalising seats/buses & online abuse is something these guys could end up with a criminal record for - nobody wants that. Hopefully the ban has made them realise that 'actions have consequences' that could have been worse for them.
If the ban is lifted, after this dialogue, they cone back, enjoy the game (although in fairness, that's hard to for any of us right now!) & behave themselves, that's the best outcome.
