In other words, it’s (basically) impossible for you to send the torrent data to someone else.
I don’t know how (in)accurate this description is, but I’ve been seeding hundreds of GB since Mullvad dropped port fwd. Same for the old times when I didn’t bother using a VPN, I never had to enable port forward in my router for it to work.
That’s why I said (basically). If another user has a port open and you connect to them through their open port, a bidirectional connection gets established and then you can also upload. But if the other user also didn’t have a port open, then BitTorrent wouldn’t work. You rely on other people to have ports open, if everyone was using mullvad, then it would stop working.
You could read a bit about NAT, which your router does, if you want to know more. But yes, of course only the initiation requires an open port, otherwise like you said, it doesn’t make sense. As soon as a connection is established your router knows where packets should be sent and an “open” port is not necessary.
