There was some nuance here. They blocked the abilities of the humans to communicate when achieving that result. So no talking or even gestures, only communicate like ants do.

Since we are so used to communicate when collaborating, it's unsurprising that we fail at collaborating when that is taken away.

This is a very cool study. But the conclusion is probably more nuanced.

While that is true, the paper shows more video and experiments that they did. they show that a single person finishes the puzzle way faster than a group of people. I agree it could be interesting to check how a group of people, sufficiently able to collaborate, would solve the puzzle. Would that be faster than a single person?
