That's precisely the situation - perl-modules provides quite a lot of
(obviously unversioned) perl module names, and then later releases of
those modules could be made on CPAN and packaged.  Sometimes other
packages depend on the more recent versions of those modules.

This is done so that 'perl' can depend on the precise versions of the
modules which it was shipped with, but it has other problems (like
circular dependencies which breaks piuparts)... the Perl team has been
talking about whether there are other ways of doing this, but there
haven't been any better ideas yet.
