Because typographic borders often have different glyphs for each side. They could
either align differently with other glyphs, or show different (typically symmetric)
ink. I suppose you could argue
that a layout engine should recognize when a U+2500 is used for a left side and when
it is used for a right side, but that seems a bit too much for me.

Right/left are already distinguished, without me doing anything. I am asking for
top/bottom. I suppose you could turn around your question using top-to-bottom vs.
bottom-to-top writting; naively, I
would answer: just transpose the effect of RTL vs. LTR on the characters for
right/left.
