However, the code was merely breaking out of the switch statement rather than doing a continue, so the remainder of the loop body after the switch was still executed. If the first action opcode contains an F_NOT but not an F_OR (such as an "untag" action), then match is toggled to 0, and the code exits the inner loop via a break which aborts processing of the actions. To fix, just use a continue instead of a break.
