AbigailII: swapping of the dice is still legal even if you have to move both dice and the highest dice when you can only make a move with 1 die ...
for example you are 3 steps away from a piece of me .. i roll 4+3 ... do i have to move the 4 first and thereby miss you ? no i am allowed to move 3, sending you to the bar, and then 4 with the same piece
so also on sites where the rule is applied you are still allowed to swap your dice
