Yeah I see your angle on re-reading!
I still think that there is no limit as long as you have adequate airfields between your destination and your destination alternate to satisfy this rule quoted here a couple of times;
"the maximum distance to an adequate
aerodrome for each two-engined aeroplane type or
variant operated, not exceeding VMO, based upon the
true airspeed that the aeroplane can maintain with
one-engine-inoperative"
I don't think this says that the destination alternate is the ONLY adequate airfield that you can take into account when diverting from your destination airfield. Why couldn't you have one or more adequate airfields between your destination and your chosen alternate to satisfy the JAR requirement of not flying beyond 60 mins on one engine from an adequate airfield?
All theory though.........!

ps Popay,
I don't think the original question was assuming a divert at destination on one engine, if it was then I agree with your last sentence.
