Just so.  For example, Mongolian (strongly top-to-bottom) is rotated
clockwise to embed it in Arabic script, but counterclockwise to
embed it in Cyrillic or Latin script.

Spell it out:  "In vertical mode, 'left' means 'top' and 'right'
means 'bottom'"

(If indeed this is true: is it true of vertical Ogham, which the
Unicode Standard (wrongly, in my view) says is strongly bottom-to-top?)

Is not the line-height of vertical text in fact a horizontally measured
