No problem. If the requirements of version 14 are present in mga2, then
the backport will (very likely) continue to work normally. If the
versions of the required packages change, they will be updated with the
upgrade. Since version 13 of mga2 is less than the version 14 of the
backport, it won't be installed.
If by chance the newer versions of the required packages don't provide
all the functions required by the backport, which is possible, then the
backport will not function completely, or maybe not at all. This is a
risk of the backport, but by restricting backports to those for which
required packages are present in subsequent releases, we lessen this
risk, relative to no such requirement.
We could say that backports will "likely but not necessarily" work after
a release upgrade.
