This actually happens surprisingly often in 6502 code, because unconditional branches always take three bytes, unlike conditional jumps which take two bytes. So

This actually happens surprisingly often in 6502 code, because unconditional branches always take three bytes, unlike conditional jumps which take two bytes. So if the value of some condition flags are known to be constant (e.g. ORing with a nonzero constant always clears the zero flag) it saves a byte to use an always-true conditional jump in place of an unconditional jump.
