"vertical first" vs. "horizontal first"

[dummzeuch 1664]

I just got confused because CnWizard uses "vertical first" vs. "horizontal first" differently than I though was correct:

 

Is "vertical first" really this ?

And is "horizontal first" really this  ?

 

I would have thought it the opposite.

If you read it as ODER BY ROW, COLUMN it makes sense, but I am not sure that it matches the actual context.

It might be relevant to remember the authors of the wizard are Chinese who come from a different reading environment than western European. They read top to bottom, right to left. So, like Uwe says, they would think of row-oriented reading as vertical since you read all of row 1, then all of row 2, etc. And that's vertical from their perspective.
