Neither of your examples really mean to increase; they just mean to repeat something. reinforce means to enforce again, and refried fairly transparently just means fried again. It just that both of those actions are additive, and doing it again means increasing the effect. Revaluing something on the other hand is not additive.

This is wrong. Refried beans are fried only once. And you can reinforce the first time.

Wikipedia claims that the refried of refried beans is a mistranslation; at any rate every dictionary I've looked at says "refry" means to fry again. I should have been more careful in my wording for reinforce though, I meant to say that it is etymologically derived from the meaning of enforcing again/providing additional enforcement, though the modern meaning may have shifted as the spelling is different from "enforce" and people don't recognize it as "re-" + word but as an indivisible unit.
