It's a little unclear, but probably not.

The description goes that they quantum lock when observed by *other* beings.  It seems unlikely that they lock when observing themselves.

I mean, they're said to have evolved the trait as a defense.  It's a pretty poor survival mechanism that renders you permanently immobile and functionally non-existent if you should ever catch a glance of yourself in a mirror.

That said, it's actually a little bit weird, for the same reasons, that they can quantum lock each other, but that does clearly happen.
