I think that's exactly what they're worried about, though. There wasn't much chance of confusion before, so it wasn't a big priority. Now that vegetable alternatives like the Impossible "patty" are becoming indistinguishable from beef, they're more concerned. If McDonald's or some other giant purveyor of beef could switch and save money, they would. They're rightly worried about a loss of market as the meat alternatives get better at mocking the real thing.
