Unfortunately, you are absolutely wrong. Midface height IS nasal height. This is how it is defined by all physical anthropologists and maxillofacial surgeons. Infact the greater the nasal height, the SHORTER the distance between the nasal base and the upper lip generally is. A short midface is usually associated with a long upper lip/philtrum ala William H Macy.
The midface is only the nasal height according to the rule of thirds, otherwise it's the region which comprises the nasal/cheek bones as well as the maxilla.
The "perceptive midface" is the region between your eyes and mouth - when someone says they have a "long midface", they are usually referring to this.
Short nasal height doesn't mean long philtrum, as that neglects all the cases where both the nasal height and philtrum are too long/short.
If the guy in your pic was to get an intense lip lift to reduce his philtrum, he would be left with overexposed gums and thus would need maxillary impaction.
