I do not understand.

If a program changes its mind it is because the evaluation of the new move is
better than the evaluation of the old move.

In most of the cases that the evaluation of the new move is better than the
evaluation of the old move the new move is better.

A different move does equal a better move in most of the time.

One extreme example:

Without pondering the program may choose the move with evaluation of 0.00(second
move in iteration 8) and with pondering it can choose the third move in
iteration 8(evaluation mate in 8 for the program)

The choice may do the difference between a win and a draw.

Usually the difference in evaluation is smaller but if the move is changed it is
clearly more times a better move than a worse move.
