Hi,

I think this is possible. One example (off the top of my head) would be if you wanted 
to tile a texture accross the geometry
(please correct me here as I am a bit of a novice). In this case your texture 
coordinate array may only have 4 values ( 0,0 0,1
1,0 1,1 ), and then via the indexes, these tex coords are applied to your vertices 
(with many vertices having the same texture
coords).
I hope that made sense.

Cheers,

Brad
