You are right - the reftest is now invalid. This was written for the
2009 version of the spec.

Yes, this looks more or less right.

One issue, though: It's displayed almost perfectly in IE10, but
something seems to be off by half (?) a pixel or so. Looks like font
anti-aliasing. You could avoid the issue by replacing every two-letter
"word" with a regular block of width:2em and height:1em with blue or
black background. No need for the Ahem font then. Alternatively, you
could try using Ahem BOTH in the test and in the ref, but that may still
be tricky to get right.
