Stream availability is part of the metadata. Metadata remains behind
even after streams have become unavailable for two reasons. First, so
iPlayer can show you when something was broadcast; second, to cope with
repeats.
And you will find that metadata usually pops into existence *before*
streams become available*. This is partly because metadata for whole
series are often imported at once, and partly because the back-end isn't
just used by iPlayer, it is (or at least, it was back when I was working
on it) also used to provide data to third-party EPGs and other internal
BBC systems.
* the one real exception I can think of is when stuff goes straight to
iPlayer without being broadcast, such as when Zoo Quest was imported
from the archive.
