They won't be removed, they will just not be upgraded and not considered
to fulfil dependencies of other packages.
One problem with the OP's pinning is probably that the order is the
wrong way around. Downpinning should happen first in the file, otherwise
things don't work (AFAICT). If I am not mistaken, the manual pages could
be wrong there, I could take a look at that later.
In any case, our pinning implementation in APT is not really understandable
or easily predictable for anyone. And slightly buggy in some corner cases
IIRC.
