Unfortunately I can't edit or delete the original comment.
Seems like he's at least partly using it for some self-promotion.
Yes, he should have lied about the fact, as a real professional would.
However, there is a huge difference between "lying", and choosing good phrasing (or even omitting unnecessary information), and your comment strikes me as very naive.
And I would understand it too if a guy had to quit working for me due to "out-of-control family reasons". Let's be honest: everybody would do it if they had to. Imagine your child being heavily sick or something. Would you continue working on some project when you are needed thousand of miles (or lots of hours) elsewhere?
As for the people that would mind those kinds of things, I wouldn't want them hiring me either. For one, they could have made my life hell afterwards with lawyers and claims...
