Sort-of, I agree.  The problem with the current description is precisely
that it uses copying rather than aliasing as a basis, but I assume that
is for C programmers.  There is definitely a problem in trying to explain
something in C-friendly terms that is conceptually outside C's rudimentary
array model.

The other possibility is to stress that the copying can occur at any
time between the initial call and the Wait.  That is, after, all precisely
what asynchronous means in this context!
