I don't think he's arguing that there's not focus confirmation, just that you don't really know what the camera has focused on (and even with the new X100 firmware, misfocus can happen).
Of course, a rangefinder will show perfect focus, but any alignment issues mean that it's lying to you. And I've only had one DSLR that didn't have some front/back focus issues with some lenses (or all) - and a DSLR screen is small enough that you can't necessarily tell if focus is absolutely spot on.
I can't say that I've missed my intended focusing point once with my x100 in 2012 so far.
