Why is it the PC + 2 + offset?

PC+2 will take you to the next instruction as we have an 8-bit offset

Haven't the PC already incremented by 1 in the default IF in w450.v, in
which case branches should use PC + 1 for the skipping the offset? Or is
the + 1 in IF disregarded?
Also, either case, I think the PC for not-taken should be PC + 2 or PC +
1 rather than PC?
