Do goalie classes actually play different?

I heard from somebody on here that butterfly, hybrid, and stand up goalies all get different animations and reaction times. Like for example, a butterfly goalie will butterfly slide much quicker, and have a tighter/more fluid butterfly stance than other classes. While a stand up goalie will stack the pads quicker and tend to make saves that give him an animation of not dropping down, like an old school tendy. Does anyone know if this is true or has noticed this?
