ELI5: Razors - why does the little blue lube bar come after the blades? It goes squeegee, blades, lube strip, instead of the opposite - why?

~~The squeegee is to clear excess shaving cream before the blades get there.~~ Since you presumably have some sort of shaving soap or cream you don't need to moisturize more before the blades do their job. The moisturizer bar comes afterwards to help re-moisturize once the blades clear away the cream/soap.

Edit: The squeegee thing is actually called a guard bar and prepares the skin for shaving by smoothing it and making it taut.
