I think what he means is that Tai Yasue will be doing the heavy lifting, while Nomura is more hands on with the FF7 remake than KH3.
Just based on Tai, Nomura isn't even in Osaka a lot of the time, so he can't be right in their faces to begin with, even if he checks on development periodically.
But if the majority of development for FFVIIr is done by external studios like CC2 isn't it exactly the same? There is probably a development director or co-director they simply have not announced yet.
