Cycling Through Glyph Classes not working

The font I’m working on has one set of alternates every lowercase letter, and I’d like to cycle through them even if they are not connected, so I followed the tutorial “features part 3- Cycling through glyph classes”. But I don’t get the desired effect. In the tutorial example you see all different ABABAB, so I would expect to see cycled letters for my default and alt sets, but I don’t. I am only getting the cycling when the letters are connected, and then in this example, I keep getting the Alt Y… What should I do to cycle it for every other occurrence?

Your question is answered in the Advanced Conextual Alternates tutorial, please read it to the end:
