True. So long as you know what's really going on it isn't a big problem.
There have been countless other flubs as well, such as the Pokedex calling Tyrogue the evolved form of Hitmonchan and Hitmonlee, Brock admitting to having a Ninetales once, and Brock saying he lived in Flint City. We all know this isn't true, and granted, they mostly appeared during Pokemon's slowest hours (Johto fillers), but it shouldn't bother you if you still understand what they mean.
Like SBaby said (sorta), 4Kids is a company. A company's main focus is to do one thing, and that's make a profit. Errors like that are not usually important, it's the amount of capitial they can produce while staying profittable. Also, since no one else'll take up the job (especially after so long), 4Kids is all we're gonna get. After all, it could've been worse.
