Campagnolo Chorus/Record Medium/Long-Cage Derailleurs

What is the difference between a campyagnolo medium pulley-
cage derailleur, and a long pulley-cage (triple)
derailleur, and why does this difference make the
pulley cages incompatible between the two derailleurs
?? I'm speaking about the 9/10 speed derailleurs, year
2000+. Thanx,

Incompatible to do what? With what?

According to the Campagnolo catalogues, the (short/medium)
and (long) pulley cages cannot be switched on a single
derailleur parallelogram. I was wondering why. Do the
derailleur parallelograms have different pulley-cage bolt
sizes ?? Do the derailleur parallelograms have different
slants to the paralellogram ?? I was wondering why this parts-
switch cannot be made.

Gee-whiz, hate to be cynical but I think they say that
because they want you to buy two RDs. Maybe Peter Chisholm
has a clear mechanical perspective on this.

The only difference is the cage assembly length. You can
make a medium cage a long one by bolting on the
appropriate assembly.
