You're correct, and the world would be much better place if UX design was conscious of that distinction. That said, I think GP was talking strictly about "intuitiveness for newbies" being opposed to power. Unfortunately, even modern developer tools are being designed as "intuitive for newbies".

EDIT:

I think a good example of intuitiveness aiding power would be shortcuts in Vim vs. Emacs. In Vim, shortcuts are created as a grammar, and they're to a great extent consistent. They tend to form "verb modifier(s) object" combinations, and each of the components can be learned separately[0]. Whereas in Emacs, there are bunch of conventions, but beyond that, shortcuts tend to have a form "modifier verb-phrase", with "verb-phrase" mapping directly to some command. This results in much less consistent - and thus much less intuitive - set of keybindings.
