Come on autists. Think logically here. I went over this once before. This is a bitwise operator and it is intentional.
1 & 1 = 1
True & True = True
This is used in logic and computing quite a bit (punny, I know).
Bill: Suzy, did you eat dinner?
Suzy: Bill, I did not go without dinner. (true statement)
Fred: Bill, did Suzy eat dinner?
Bill: She replied in the negative (true statement)
Two statements, although contradictory, can both be correct.
