You seem to be confusing schemas and users --- they are not the same
thing at all. The above grants the right to lookup objects in schema1
to the user (a/k/a role) named schema2; who doesn't necessarily have
anything to do with objects in schema2.
Also, although you failed to show the specific command that was failing,
I suspect what you are actually running into is lack of CREATE
permission not USAGE permission.
