Do you imply, they therefor shouldn't be linked together?
I was - btw - referring to this: http://www.jugglingedge.com/smalltalk.php?ThreadID=2088&SmallID=14886#Small14886 ( [#n ball] "horizontal split multiplex", lukeburrage).
I also believe, some slight differences in many siteswaps can hardly be described by siteswap-notation only, like `galloping´, slight delays, different dwell-times for different throws, squeeze catches(?), .. so siteswap hardly ever describes an actual juggling act wholly exactly.
I'm also not sure, that [43] couldn't be done without squeeze catches - i e.g. spread them by different lever (but I don't know what exactly a "squeeze catch" is).
