If I understand this correctly, it's only a interpretation thing.
Before, the short tag "GPL-2.0+" pointed directly to a license "GNU General Public License v2.0 or later"
and "GPL-2.0" pointed directly to "GNU General Public License v2.0 only".

Now with the new  "License Expression Syntax", the term "GPL-2.0+" must be
first interpreted, and the result is something like "(GNU General Public License v2.0 only) or later",
which is actual the same as before (at least for me as non-lawyer :-)

I don't think so. I guess the reason behind is to make it easier for e.g. automatic license
checking.
