I don't actually expect goalies to make stops on pucks that are deflected once or twice. Which I think it possibly was two deflections on way to net. Close in deflections in anycase with even medium velocity of shot it would be beyond reaction time to get those or to ascertain where the puck is headed. Making yourself big and coming out a bit are options to increase chances of stops but its often crapshoots with deflections.
Your post is confusing to me because goalies are unable to effectively track close in deflections in anycase. Human visual response time is not that quick to be able to do that with deflections close to net. Goalies may guess right,
In fact most of what I see goalies are told to use blocking save instead of reaction save on deflections. Because you can't really react to a close deflection at medium velocity shot.
Before goaltenders can make a particular type of save, they must first size up the situation. Athleticism & puck-tracking ability is also a factor.

Some hockey people think that a goalie can track deflections and design things like this to work on reactions.

The trouble is that ramp is uniform and deflecting the shots similarly, not as in real game deflections where the puck could be headed anywhere, and high or low.
The mere fact that teams and players practice the art of deflection and pass shots as much as they do is it tricks the goalie, and/or changes angle of where puck is going. Added, deflections off point shots are even more difficult as either the original shot, or the point of deflection, or both, may be screened.
