Correct in this case, however the name of most standard functions 
describes what the functions do.

Good explanation.
Still, the name "move" is somewhat problematic, if even Bjarne's 
description of the function has to explain from the very beginning that 
std::move doesn't move anything.

So, yes the name is not perfect, but alternatives could be worse, and we 
can live with not perfect.
