Pick some simple protocol. Draw a sequence diagram of what it does for the 2s:2s case, using a clock skew of 0s. Now draw sequence diagram of what happens for the 3s:1s case, using a clock skew of 1s or -1s (depending on which direction you put the asymmetry in).
Both diagrams contain the exact same interactions. The protocol will return the same thing in both cases.

I had a sign wrong last night, which suggested I'd solved for the difference between the two latencies. Actually (of course) I'd solved for the sum of the two latencies, which as the article mentioned, is all you can really determine. facepalm
