My guess is, if the duration of the AB transition equals the duration of the
new transition, then authors want case 2 if C is close to B, and case 3 is C
is close to A.

Hmm. I think Maciej was on the right track and we really want to specify
velocity, not duration, or perhaps a desired velocity and a maximum
duration. It's too bad that specifying velocity in CSS seems hard :-(.
