Lease limits make a class a "billing class".  A client can be matched
by several classes that have lease limits, but only one will be billed
for that client.

Note that a client need not be billed to the class in an "allow"
statement for it to be matched.

Yes, it is by design that a client may match multiple classes, if they
are set up that way.
