Obviously we mean different things by "sub-license". Can you explain
what you understand it to mean?

If X licenses a work to Y under licence L1 and Y licences the same
work to Z under licence L2 where Y's right to give L2 is given under
L1 then L2 is a sublicence of L1. That is the situation you are
describing. And that is (as I understand it) what "sublicence" means.
