I thought about that, because in Eastern Europe, where I live, they are pronounced similar too. Still, I can't believe someone measured the pros and cons of that match and thought:
"Well, even if the only reason for that match is phonetics, let's fuckin' do it! It will be lots of fun if Musasi wins...or was that Mousashi? Haha, bookies will love the confusion..."
Ah, enough bitching, at the end, I'm already curious what will happen in these matches, so maybe it's a good decision after all
