Why is that counter-intuitive? Makes more sense that the harder the
tire, the ability to channel the water is better. Less tire pressure,
more surface area to plane.

You're clearly correct. Now I'm not even sure why it seemed backwards at
first thought. Something about a smaller contact patch providing a bigger
contact patch I guess.

For a given combination of tire and vehicle, pressure that's too low will
allow the tire to roll with a hollow spot on the road. Water will collect in
that hollow rather than be passed through. I saw a brief video of this once,
and I may not be describing it right.
