This is correct, the contributors own the copyright.

I know you say "basically", but I think it is important to point out that 
under the new contribution terms, everybody who submits still keeps the 
copyright, like they did before.
Everbody who submits data does give an unlimited licence to the OSM 
foundation. This means OSM foundation can do everything it wants to do with 
your map data, without asking you. This doesn't mean OSMF gets copyright, 
that's the one thing you keep.
Not owning the copyright means that OSMF cannot transfer the copyrights (duh) 
and that it cannot sue people/companies/... for copyright violations.

Sadly the contributor terms require an unlimited license (like I said above). 
And it is that [profanity removed] unlimited license that is incompatible with 
the ODbL and about any other existing license except public domain.
