You seem to be misunderstanding what "relicence" means.  It means to
issue a new licence.  If an existing licence says you can additionally use
somethinng under the terms of another licence (as with LGPL -> GPL, or
GPLv2 -> GPLv3) then this is not relicencing.  No change in the licence
text has occured.

Precisely.  Sublicencing is not relicencing, and relicencing is not
sublicencing.  This is why we have different words for them :)
Additionally, dealing means to deal and distribute, not to change what
conditions you were supplied it with in the first place, otherwise there
would be no need to have a licence text at all.
