I think that article gives an explanation as to why if ever the "hot water"
freezes faster. Yes, it's news to me but it's not categorically stating that
water in the "hot" pipes will always freeze faster.

Yup.
The hot water heater reduces the dissolved minerals slightly, mainly
carbonates; enough to make a slight difference in the freezing point.
