This is a pretty bogus statement if you ask me.

A hypervisor a software system that provides seperation between
protection realms.

It also handles exceptions and "system calls" on behalf of the other
protection realms.

I personally don't see the difference at all. And since many
hypervisors even do cpu scheduling, the fundamental differences
converge to almost nothing.
