Actually, you do have to teach most high schoolers (actually most people) what "A or B" means. The common usage reads that as "A xor B"

A very good point. I still think it's a big win if it makes it 1% easier for new programmers to understand.

I actually think "and" and "or" make it 1% more difficult for new programmers because it doesn't implicitly warn them about things like short-circuit evaluation and whatnot. "and" and "or" have a lot of nuances that experienced programmers take for granted that a new programmer won't know until they're taught.
