Ah, 'last' means in the last layer; I had not realised that the layer 
order had any meaning at all when it came to menus. I had in fact made 
exactly this mistake and got this result, but I didn't know the reason. 
Thanks for the clarification. I think the rule therefore is:

if the topmost (highest numbered) menu button in the menu group is 
called 'Help' (or presumably the equivalent in other human languages), 
then this menu gets used as the rightmost menu in OSX, and all is as 
expected. If another menu button is topmost, then that is seen by the 
IDE not to be a 'Help' menu, so it helpfully (!) adds one itself for 
OSX to use: this menu will naturally enough not contain any items which 
the developer may have put in his/her own Help menu and is therefore 
useless. Is this right?
