why high to low, look out below?

Only that the "high to low, look out below" phrase in piloting texts
generally refers to pressure effects, not temperature effects. That's
the only sense in which I disagree with the cited article.

In texts that avoid going in-depth, you're right that they ignore the
temperature effect. But other references use it for both meanings, and
it's knowledge worth having.

Type the phrase into Google, and you'll find many sites, including AOPA
and at least one aviation mnemonic collection, that use it for both
pressure and temperature. A lot of us learned it that way, too.

I thought Mr Duniho did an excellent job of explaining both effects to
the OP.
