It might also imply 23 dientes chain wrap but that is not clear to me.
There is no way ever, in any configuration, that an NR or SR derailleur (or the Zeus derailleur under discussion here which is an almost exact copy of the Record/NR derailleur) could handle a 36t freewheel cog. These derailleurs have been around for 50 years now. Their capabilities are well understood. So if the numbers refer to cog sizes they are either ridiculously wrong or they don't refer to cog sizes.
