No that isn't true. It is the C2DM mechanism. Android since 1.0 has had a single constant connection to google services to receive "tickles" when there are things to do -- single email or contacts, etc. One of the tickles is to perform app downloads. This is the exact same mechanism the C2DM is. It has been there since 1.0 for the Google applications, and was only ready to be exposed to third party developers in Froyo.
(Also fwiw this is technically not part of the Android platform itself, but proprietary features that Google supplies to developers on top of the platform.)
