I've read this a couple times but practical experience
says this is not true. If it were true, I'd be able to mount
a belt on a crowned pulley by just holding it to the pulley
and turn the pulley.
I've never been able to have this happen. In fact I see
just the opposite. The belt keeps pushing off the pulley,
as one would expect. It just doesn't want to ride up
onto the pulley and over the crown. I always have to
get a small amount over the top of the crown, by force,
before it will pull itself on.
