I think (it's been a while) that this was about whether the computed position
would be the start-edge or the end-edge of the box - i.e, in the (ltr) example
used previously, would the start-edge (the left edge) be at the computed
(x-)position, or would the end-edge (the right edge) - because of the end
alignment.

Another way to put it may be:

"pos" is computed position,
"." is outside cue box,
"-" is inside cue box,
[] is viewport edge,
| is cue edge.

dir:ltr, pos:25, align:start ->
start-edge at 25, text "grows" to the right : [...|Text--------]

dir:ltr, pos:25, align:end ->
start-edge at 25, text "grows" to the right : [...|--------Text]

OR

dir:ltr, pos:25, align:end ->
end-edge at 25, text starts at start-edge (25-size) and "grows" to the right : 
|--------T[ext|...........]

Better? Worse?
