[css-writing-modes] TCY glyph size/positioning

I'm looking at a copy of Mac Fan, and notice that the digits in their
TCY are the same height as a Japanese character.

If the text were typeset as horizontal, they would be somewhat shorter
than 1em and shifted up somewhat from the bottom of the em box, because
digits in horizontal text sit on the alphabetic baseline.

The rendering in Mac Fan is clearly better, but how does it work?
