The creator of an original work is recognized as its owner, and granted 
sole authority over how that work may be distributed.

Licenses may differ by licensee.  In proprietary software a common 
example of this is site licenses, where the terms often differ 
significantly from those in individual licenses.

The owner of a work may grant different terms to anyone. Some pay more, 
some pay less.  Some can copy to multiple machines, others limited to 
one machine.  And some may be granted a right to have access to the 
source code, and others may choose a different license that doesn't 
include that right.

The existence of one set of license terms with one customer does not 
negate the license terms with another customer.

This is equally true regardless whether the distribution of source code 
is among the terms of a license.
