The system doesn't differentiate between meal start and end work when it comes down to it. It's just an in/out punch. Or so I've heard an HRTM say; doing so shouldn't be a workaround for compliance, since the system would still show that 5/6 hours has passed from shift start to clocking out.
It's true that the system only counts it as a punch (myTime doesn't say what button you hit), but since you'll have a missing punch when you go to fix it you can put your "start meal" before you would've hit compliance.
