I'm afraid that if the previous stanza wasn't delivered for some
reason then
receiving pong response will not show anything useful.
It's possible, I suppose, that the remote client went offline before
the <message/>, and came back online after, just in time to get the
<iq/>, but it seems terribly unlikely, especially as you'd also see a
<presence/> update as it came back online.
