It’s not great phrasing I agree… but it is a common way to describe it.
It’s the action that matters not the description.
If “she” (not clear who) moved her head back and forth in a vertical rotation, it doesn’t matter if you call it “shook her head yes” or “nodded”. The meaning is the same.
If she moved her head back and forth in a horizontal rotation and this person interpreted that as a “yes”, then that is insanity.
It’s just not the accepted and used English for those actions. If it was something like “rotated” then it would be ambiguous and subject to interpretation, but the word “shook” already has a meaning
So it sounds like you’re just not familiar with the phrase. It might not be “accepted and used” in your area, and I agree it’s confusing. But it is common, regardless.
Many examples can be found in your choice of search engine, here’s one result but it’s very very common.
“She shook her head yes”
This line is all you need to see to know that this person is a moron or a lunatic.
You don’t shake your head to say yes.
Some people use that phrase to mean “nod”. It’s the same action just a different direction.
And their point is that they are wrong to do so.

Not only is “common” unfortunately not a quantitative assertion (and I disagree), many incorrect usages are “common.”

As earlier stated, obviously some people might use the opposite words for a particular effect.
I mean feel free to count search results if you care to assess exactly how common it is. Regardless, writing this phrase is not “insanity”
I’m pretty sure I only said it was wrong.
some cultures do, just not ours
