Having full lips is indeed ideal for both sexes, so you're right in that sense. However there's a big difference between what that person has and what I'm talking about.
Here is an example of the ideal position of the lips (this is pretty gender neutral, it does vary a bit between men and women but you get the idea):
What his does is curve up and close the nasolabial angle to become accute. In men it should be 90-92?. Now I'm not saying this should be like that on ALL men. The model you linked looks to have an angle that is more acute than 90? - but it suits him. Ultimately it's going to depend on the individual. In this case it made the patient look retarded.
Moreover, using models to illustrate an example reeks of puahate. Models do not exemplify aesthetic ideals, rather they possess extreme features and represent passing fads and trends within the industry itself. Plenty of hugely successful models look like average people if you were to see them in the street (see Simon Nessman or Francisco Lachowski). Others simply represent a unique look that people can associate with a brand (David Gandy's piercing blue eyes and black hair).
If the patient wanted or needed fuller lips then perhaps this would've better been achieved through the use of fillers as opposed to messing up the nL angle. That's my 2 cents anyway.
P.S. I apologise for saying you negged me if you didn't.
