JET (WMH) buys from anyone who has stock, even if they put their own nameplate on it. Pretty much the norm nowadays. You need a motor manual, or the diagram to do the conversions. You have the diagram.
Pure speculation, but given that the starter windings have their capacitor and the run windings theirs in a cap-start/cap-run motor, the multiple leads might be for them. Don't know if they have cap-run motors in the 240V area, but never looked. As I understand it, some dual-voltage motors don't separate their windings in the 240 option, running in series instead. Betting this would play hob with the run capacitor, so maybe that's to maintain start/run in parallel.
Oh well, such as it is, my 2 kopecks.
