Yes, you are right. On the other hand, if the heated bed was bow for some reason, clipping it down tightly on all 4 sides may not be a good idea either. We used glass for printing because it's flat, doesn't easily bow and maybe other reasons. These plastic clips hold the glass in place on the bed re: X and Y axis so it doesn't shift left/right, or front/back. I only use one clip just to make it a bit steady, should the bed is physically bowed, the glass is still flat and won't be force into a bow form by additional clips. Nothing is perfect, but these clips do solved 2 of the problems I encountered.
