Not so good: while it became a writing-mode-independent, it's still a 
layout-algorithm-dependent: now it is defined in terms of flow layout.

It might be better to use "logical width/height direction", or simply 
"width/height direction", because the direction of physical width/height 
always remains constant.

Did you consider "logical-top" etc. instead of "before" etc.?

Those before/after/start/end is really inconvenient for authors, and 
probably for Japanese authors too. I would suggest reusing the terms 
from both worlds instead of introducing unusual terminology:

    top          logical-top         japanese-left
    left         logical-left        japanese-bottom
    right        logical-right       japanese-top
    bottom       logical-bottom      japanese-right

In this case, logical-top and japanese-left are full synonyms and can be 
used interchangeably throughout the specifications.
