Yes, that's another source of confusion.  Upon startup, an soffice 
instance tries to connect to a "named pipe" with a well-known name (and 
sets that pipe up in listening mode if it does not yet exist).  That 
way, only one instance will ever be running for a given installation. 
The well-known name contains (a hash of) the user installation path, so 
whenever two installations would share a user installation, they are 
connected in this way.  (See desktop/source/app/officeipcthread.cxx for 
details.)
