What a waste of an animation. It doesn't really show you anything and I suspect a large portion of the reason for that is because the words aren't in English.
Here are the "facts" about a 2 point strut bar.
1.) If your strut towers are flexible, at all, to move under cornering then a 2 point bar is going to move the towers in the same direction. It will NOT keep one from moving and not the other. Think of a cardboard box with both ends open laying on it side. How easy is it to push the cardboard box over? That is all you are doing with a 2 point brace. If one tower moves, they both move in the same direction which doesn't improve stiffness at all.
2.) The only direction a 2 point brace will keep the towers from moving at all in is braking and acceleration of which only braking produces enough force on the towers to possibly move them.
3.) By tying the two towers together with a 2 point brace you may change the chassis's resonance frequency and reduce some NVH like cowl shake. Which is 99% the reason why Ford put them on the S197 chassis and is 99% of what people "notice" when they put one on.
Reality is, for any performance enhancement, a 2 point brace will only lighten your wallet, bling up the engine bay, and add weight to the nose of your car. If you want a REAL advantage in stiffening up the chassis, you will need to triangulate that 2 point brace to a point on the chassis that is out of plane with the motion of the strut towers... say... the firewall. Guess what, the 2015 Mustangs did EXACTLY that! By tying into the firewall you now reduce the deflection of the towers substantially.
Also, the S197 chass's rigidity is such that a 2 point brace isn't doing much at all. You might see some slightly better numbers on a flexible chassis like the SN95's and Foxes but I doubt highly it is enough to improve handling or substantially increase rigidity. A three point brace definitely decreases tower deflection (if there is any at all).

It might make a difference, but nothing like the difference FLSFC will make.
FLSFC's on the S197 chassis? Why? I can jack up three wheels on this car from one jacking point and the marginal increase in rigidity from SFC's is so tiny the only use for them is as a jacking rail.
