That's true: an extra complication! However, I have only seen that for one-
or two-digit numbers.
This is also used for single letters or two-letter acronyms (such as "Km").
Probably this is the reason for the "squared letters" in range
U+3380..U+33DD (some of which are 3-letter long, BTW).
But that would a limited case for horizontal text embedded in vertical text:
I cannot imagine a real-world situation for a vertical text embedded in
horizontal text.
