I agree that there is a distinction, but the latter is true on most
systems that support only one identifier too, and is in fact consistent
with how OpenID was originally described: OpenID allows you to prove
that you own a URL. One application of that is to prove that you own a
user account that references that URL, which is a special case of
asserting that you're the same person I saw last time. (for some
wishy-washy definition of "person".)
This is the main reason why I make a point of saying "identifier"
instead of "identity" in this context. My identity is a more abstract
concept that is difficult to define.
