That sentence above is meant that completion in plain Emacs is taking
place in the minibuffer. Words are expanding in the minibuffer and
words are completed in the minibuffer.

That separate window, as separate and important subject, is opened
during completion process is great feature and I hope icomplete will
adopt it.

Helm completion does not complete in mini buffer. One can write
anything in the mini buffer so words are not expanding in the
minibuffer. Instead person is making choice in the separate window. I
hope you see that.
