So I'm learning the guitar with someone's help, right?

He keeps telling me I’m doing it wrong, even though he’s doing the exact same thing. I already know how the initial mistakes in playing happen, so there’s no need to explain them I just want a clear answer when I ask. I can’t see his fingers on the strings because they’re always completely covered. He named the frets too quickly, and when I followed his example, he often took the guitar to start again.
