The copyright owner can license the code to anyone on whatever
terms - and it does not need to be the same license for everybody.

If you write some brilliant software, then you can
sell it to me on commercial terms for 100 dollars
and give it to your neighbor on an open source license.

That open source license gives your neighbor the right
to give his brother a copy under the same license.
But because he does not own copyright, then he
can not pass it on under another license. That
privilege would be yours as copyright owner.
