And you would be judging incorrectly by rule.

See NFHS rule 4-23-1. Guarding is a defender legally placing their body in the PATH of an offensive opponent. If the defender is at the side, he can't be in the path.

B1 may have a legal position on the floor, but he does not have a legal guarding position. They are 2 completely different concepts.
