Yes, you got that right, it does.
There's a configuration file that allows the user to specify how
to "uncompress" (and "compress") for a specific file format.

I'm running the diff's between the packages names. In the
configuration file mentioned above, one can define how to generate
the name of each filetype -- for the "Packages" file, the name
is "Packages". For for example sysvinit_2.3-2.deb, the name
is "sysvinit". But it should be easy to also include rpm's,
and any other files types.
(PS: I don't read debian-devel regularly).
