No he's saying if you are a generalist you shouldn't try to market yourself as that. Usually employers are looking for specialists that are perfectly moulded to the one exact task they need at that very moment.
It's misguided of course, but that's what they think they want and if you say "I've done all sorts of things and I'm good at all of them" they'll hear "I don't have much experience with anything" and discount you.

So it's better to pretend to be a specialist.
