To be on the safe side I would make sure the clip can not touch the piston or pad backing plate.

Edit: I looked at my front caliper and it looks like a long clip will hit the metal of the caliper and not the cylinder.

I made sure that it rotated freely after I reinstalled it, and it was not binding on anything. If in doubt one could always nip a bit off the "legs" of the clip.
