just by chance I am reading this literally minutes after havoing searched for the reason why one or the other machien seems to connect twice or more often in parallel.... took me about an hour checking, reading, understanding... that "you and 1 more" doesn't mean there is multiple, parallel connections or multiple owners of a file but indeed is nothing oto worry of as you explain above.
Definitly I want to support the Eldrin's et.al. opinion to change the current messaging/wording. I'd go so for to recommend not to reflect these "multiple" instances (which are neither connections nor owners) in the UI at all. after all: what does this information tell us on the helpful side of live?
anyway, thanks for clearing this up!
