British - apparently some US company stole my name

it's not obvious at all. There's cases where this has happened - Lallemand own Seibel, where the original BRY97 was deposited, but most of the homebrew liquid strains have their origins in US homebrewers harvesting yeast from whatever bottles they could, and then passing them around the community, mutating away, until they ended up at a commercial company. Which is why the attributions can be a bit dodgy, and why WL and Wyeast versions of the same yeast can show significant genetic variation - WLP001 and 1056 are a classic example.
Pasteurisation is far from universal - many British breweries like to have one bottle-conditioned beer for Camra-political reasons, and of course you can find most British ale yeasts in cask dregs from a pub.
Andy - it's all internet hearsay, I don't have a reliable source but supposedly the story goes that for some reason (building work?) Lallemand outsourced some production to Munton for a while and Munton kept some Notty master culture after the deal had expired. Not sure how true that is though.
Not to mention the fact that yeast suppliers don't really go around swabbing beer bottles to create their stock. This would rarely work anyway because of filtration and/or pasteurization. They obviously get their stock from other suppliers/yeast banks or complacent breweries.
