The shooters likely spend the vast majority of their time shooting a single pistol, so of course their performance would be better doing this... it is like saying shooting right handed is better, when the shooter who does the test is right handed! Not that I dispute the results personally, because I shoot with one pistol nearly all the time also, but there are trick shooters who are very good with two pistols. The correct comparison would be a sample of shooters who excel at each method and have sufficient training directly related to the task being measured (walking approach to target from 30 yards).
I was confused by the title so I had to look it up.
Generally speaking, a pistol is a handgun and a handgun is a pistol.

You have to get into the weeds to really come up with a difference. i.e. this is not the “clip vs magazine” sort of thing.
It isn’t one or two guns. It is the level of practice and training on the part shooter.
I have seen some people load and fire shells one at time from shotgun faster than I can cycle them through using a pump.
I think the person firing the weapon determines accuracy. Rate of fire only applies if you’re dealing with multiple targets in a short time span.
One shot in the chest with a .45 does wonders to discoursge an attacker.
I’d guess that the dual pistols thing was more of a single action era likelihood.
What would Hillary say? I can handle only one device at a time! (and then you find 3 or 4 in her purse)
Conclusion: stick to the silver screen with it unless you're willing to do a lot more practice than I ever intend to. If I need multiple projectiles in the air simultaneously I'll grab Mr. Shotgun.
I always liked this movie .... although i do noot think they are chambered for .45acp ... too many shots between dropping magazines, maybe .38 Super.
