Count EVERY time a spoke crosses another spoke from its exit from the hub on its lonely, pioneering journey to the rim: even that teeny, tiny insignificant cross near the flange (huhhuhhuh - he said flange). In the case of your hub / spoke setup, any spoke you care to look at has crossed paths (muhuhuhahahaa) with only two other spokes since leaving hubsville on its way to rim city- thus making it 2 cross. The terminology is just a simple description of what's going on, not somthing geeky and cliquey dreamt up to frighten people.
Disc, Alfine...exceedingly cool, but please, please do the decent thing and spend a wee bit extra on free-range. There's a good chap.
