With Kc4, the king only frees the way for the pawn, but otherwise is inactive. Next moves are needed to race the pawn for promotion.
With Kc5, the king is able to remove the f7 pawn, then free the way for promotion, and the f file pawn is still on-time for queen promotion as it is much closer to the 8th rank. So the king is more active and gains a pawn that makes the game equal after both promotion (with Kc4, white is down a pawn after both promotions, which makes the difference in the endgame).

I see. So my estimation of the position was right in so far that the King on c5 is nearer to and quicker at the f7-pawn in the end race than on c4. Nothing cryptic about it. I just had to add things together.
I appreciate your answer. Thanks.
