It's quite possible to have "same" name and same origin:
1. The characters looks the same, but is actually different. Like this example I found on the Internet http://www.miсrоsоft.com
(not the real website, but the address look the same).
2. Not the full name is being displayed. There is a cut-off character on a string of character, and anything from that cut-off character and after won't get displayed (this is why we got the SD bug with weapon name spilling on the next one: the cut-off character is not there because there is no rooms left for it). Normally you can't type a cut-off character, as it will be something not on the keyboard, but seeing how people can put in all sort of symbol in their name, it's quite possible someone put a cut-off character there manually, and what come after that is different, so you see the same name even though it's different name.
