I don't think so.  This is a scene with two simultaneous conversations; in
order to help make the subtitles readable, they were authored to keep one
conversation pair always on top, and the other always on the bottom.  Having
captions move while they're already displayed wouldn't do this.  (I think
it'd make it unreadable, actually, by adding motion into the mix.)

I don't know what degree of sameness they expect, but as users can always
override their font (implying different wrapping results, etc.), you'll
never be able to guarantee that it'll look identical to the output of a more
fixed format.  If captions have editing like the above, it could even result
in a visible drop in quality.
