True.
But thats different than saying something doesnt exist. Example: Half-Cab, Fakie 180, and Switch Nollie 180 all pertain to the same thing. But saying that 2 different grinds are the same just because theyre on the same truck? That's like saying smiths and feebles are really just 5-0s. (which we all know our beloved video game does sometimes lol)
