Yes. The cold flow properties of DOT4 LV are important for proper ABS behavior in colder temperatures.
How cold does it get. The purpose of it is to allow for very fast and accurate abs operation in the cold. But this is for when abs activates not regular driving. In warm/hot days there's no discernable difference even with that low viscosity stuff and dot 3 if you were to try to test it yourself. Scientific equipment that removes the human variable and uses electronics to accelerate and decelerate with sensors and triggers and such to get a consistent figure are used and in those tests the tire and road temperature and the ambient temperature it'll be once the tires cool down from the last run have an effect and are noted. If that m240 had to be my daily it'd have dot 3 so it absorbs less water and lasts longer. I'd never track it nor does it get cold enough for dot 3 to slow it down enough in these warm texas winters.
It's like using a 0W-30 instead of a 10W-30. There will always be a difference at 40C; whether or not it matters in Phoenix is highly debatable, but the difference does exist.
