I had this same question and we discussed it a bit on another forum. I think this may be partially a language issue, but my take is that he uses Novation and automap works in an intuitive way with Padshop and Retrologue, so it is a simple/intuitive thing to use the keyboard with those plugs to create patches. H4/5 has a mess of mappings that you have to do yourself and isn’t quite as intuitive for patch creation when you are treating H5 as a simple “VA”. Which is true if you look at it in that narrow use case.
So, what I got out of it is he wants to continue to create the patches in the stand alone apps and port them to H5.
I hope I’m not putting words in zizi’s mouth.
