There are per-thread resources, too. CoUninitialize in a thread frees
resources allocated for this thread when it leaves MTA apartment.

I am confused. In point 1 of the question, you think it is correct
that no resource is allocated from the 2nd call to CoInitializeEx.

I meant second call on the same thread. It either fails, or returns
S_FALSE and does nothing (except incrementing some internal counter).

Every thread that wants to use COM must call CoInitialize[Ex]. The first
such call (the first for the calling thread, not for the apartment or
for the process) returns S_OK and allocates per-thread resources.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
