No. What I think happened is Enter stole the plans for the Beet. That much is true because in the episode where it happens we see it on the computer screen. However they weren't looking to make an exact replica of those designs. They built their own Beet according to their own specifications. So it's going to look modified.

I'm assuming that as Masato and J were stealing the Enetron over time that at one point they also intercepted the plans for the Beet and Stag. So the Enetron they were stealing was used to build their mechs at around the same time Enter was building his 'improved' version. I've gotta say that I really dig the whole avatar in real life thing. Althought it still seems like an odd reason to work in Magi Yellows' actor to play Masato. Why does the avatar have to look young? Just to appeal to Japanese audiences? Why couldn't he just be the same age as the actual person? It makes the fact that old Masato is controlling an avatar of his young self seem goofy and creepy.
