Nikon is late to the party with their fluorine coat – they've got it on one supertele, whereas Canon uses it on five supertele lenses (four primes and a zoom), and more importantly on several lenses that aren't uber-expensive niche lenses (24-70/2.8 II, 24-70/4, 8-15 fisheye, 70-300L, 16-35/4, and MkIII TCs, maybe I missed some?).
Nikon shows two other 'vendors', who else besides Canon uses a fluorine coating on exposed elements? Do they even mean other lens vendors? It's possible they purchased fluorine coating reagents from two vendors (fluorine coatings are used as anti-graffiti spray on public buildings), and compared those to their in-house process. As for their testing, 500 g/cm2 is a pretty heavy-handed lens cleaning, a quick test on a lab balance suggests that I usually use 150-200 g/cm2 for a normal lens cleaning, and it is likely that the relationship between applied force and coating removal is nonlinear.
Cool video though, looks like the marketing folks had some fun with it!
