He could have also mentioned that floor(cap-height + x-height + descender) also equals 32, but isn’t the answer either. And probably a few other arbitrary arithmetic combinations would work as well. But it seems it me it’d be much more efficient to just explain the real answer instead of telling you all the ways you could misinterpret it... which is exactly what he goes on to do.
