Once you own the mutex, you own it until you release it.
Waiting on a mutex you own always returns,
otherwise you would deadlock.

<Help>
Two or more processes can call CreateMutex to create the same named mutex. The first
process actually creates the mutex, and subsequent processes open a handle to the existing
mutex.  </Help>

So, it is a different handle to the same mutex, which you own.
Still no deadlock.
