IMHO this specifies what is relevant when an emerge merging happens.
Nothing more, nothing less.
_If_ one would be willing to interpret it to have a meaning also _after_
the emerge, then of course the RDEPEND in PMS can refer to the only value
which is specified in PMS, i.e. that stored in the ebuild (and not in
any database which is explicitly not specified by PMS).
In other words: _If_ one puts any unsaid interpretation into that
sentence, then this can only be dynamic deps.
