wof - there should be no confusion.
Para 1: "Manual Braking Immediately after main gear touchdown," etc etc is simply a statement of how Boeing say you should do it.
Para 2: "Although immediate braking is desired, manual braking techniques normally...." etc etc is simply advising you of what tends to happen (refer flufdriver) and the effect of that.
Follow the book (or, of course, your company Ops Manual if different).
Para 2 is also an indication of why autobrake is a better option if distances are near limiting.
