I'd bet it happens more often than people realise, just usually it'll be far less noticeable (though I believe if necessary people aren't notified/it isn't realised it can be quite problematic if a breakdown or something similar occurs). Driver has likely read the wrong row/column on the allocation sheet. The first driver this morning simply takes the bus light (as mentioned by Dan on Facebook), and probably didn't think "this is for an X10" - if they had then they probably would have double checked the allocation before it left the depot.
