If it's an application that's managing the SSO process, then yes.
Otherwise it's probably a SSO module of some sort at the target that
manages SSO on behalf of multiple applications.
There is only one SSO assertion to get a session established, it's not a
constant process. The point is, protection against clock skew is
balanced against the desire for the SSO assertion to be short-lived, and
the profile doesn't say what you have to decide. An hour is clearly
wrong, but five minutes might be considered too short by some.

The receiver of a SSO assertion (the target) is the one relying on the
assertion.

I'm sure most implementations do (mine is currently not even
configurable in its beta form), but that's not part of the spec.
