"Ideally" that's how it's supposed to work, but isn't how it works as of
present-day.  Speaking solely about the BitTorrent protocol, upstream
does not affect downstream speed.  In fact, there's a BitTorrent client
out there which specifically *does not* share any of the data being
downloaded (thus acting as a pure leeching client):
