Eh, not really. That just means, more than likely, that he does probably the same thing I do and makes sure that his paycheck's automatic deductions are as close to dead on, or slightly higher, as possible. Granted, I don't make 400k, but the same process I follow now (I've been returned a small amount of money each of the last five years) shouldn't change as I get bonuses and promotions. The only thing that will make me deviate from my process is if my expenses increase drastically.
Though, as I write this, I remember that there's a hard $$$$ limit on how much you can contribute to a 401(k), which is the bulk of how I'm able to not owe money. I'd imagine Mr. 400k has other funds he contributes to, plus a mortgage, to make up for the limit though.
