Doubtless that is what I was thinking of.  My bad.  Of course,
horizontal scripts aren't like this: a horizontal script can validly
run from top to bottom or from bottom to top (to the annoyance
of people who interfile English and German books, for example).

My point is simply that the terms "height", "ascender", and "descender"
are biased towards horizontal layout; they suggest that the characters are
displayed in a vertical orientation.  I don't think anything can or
should be done about this.
