Yeah this doesn't seem true from the looks of it. Pat is different enough to completely stand on his own, it doesn't look he'll play remotely similar to either of the sisters. He doesn't seem to have the trademark fast mid punish, just a slow mid stab and not quite as fast shield bash. No overbearing speed and range, like Soph... that was given to Pyrrha. Really, she is more like an updated Sophie than a new character on her own. Pat definitely does not look sharper or more agile than either of the sisters.
I guess as the main character, Pat will be a basic, easy to use character with no strengths or weaknesses. Right now he looks cool, but none of his moves really stand out to me. All I see is basic launcher, basic AA, useless mid-high-mid slow NCC string, standard tech crouch, possibly useless tech jump, some low kicks which may or may not be useful, and a low stab that doesn't look reactable. Actually one thing stood out: an auto-GI. But it was really slow....
