Stupid Programming Challenge (Barry Barber)

Hello again,
Seeing as all the experts are now agreed on the script for a proportional thumb on a scrollbar, may I ask a stupid beginners question?

Why did Scott Rossi use a separate scrollbar and routine? 
I thought the method was to click the 'Vertical scrollbar' box in the Basic properties of the Group "master".
 When I did this I got a proportional scrollbar which scrolled to end of the list without scriptng anything - of which I am not yet capable, anyway!.;-(

Of course there will be some technical reason which I will not understand but would love to know.

Thanks to all for the valuable info I pick up here everyday. Must limit reading this list though and try creating something.
