I mean, there were times in my career where I was working 12+ hour days for one employer, so working 16+ hour days for two doesn't seem like that much of a stretch; still leaves you with 8 hours of sleep. I've known enough workaholics in my time to know that it ain't beyond the realm of possibility.

But yes, it's more of a plausible deniability thing. Either/both employers would need to prove that you weren't working 40 hours a week for them, which is not only impossible (good luck proving a negative) but a much higher standard than is reasonable in the first place (especially for programmers, having a full 40 productive hours a week is rare and unsustainable; half that or less is more typical).
