well that's easy, the last 2 statements get executed when the algorithm is "rolling back" the loop. I mean: the last time the first movedisks statement is executed in the loop, it will start executing the last 2 statements from back to front (read: go over the loop from back to front)... that's what recursion is all about ;-)
