No, it's the number of the last sample decodable from this page.
Yes, it counts from 1, not 0 (because 0 is a valid value to mean
'no samples decodable yet', as the headers have).

By the way, rehuff seems to produce horribly screwed up streams
with granulepos == -1 on every page (or at least most of them). 
You should probably fix that.
