Re: bar number position (direction) numerical definitions overlap

Yes, that's correct. For some layout objects, the direction property
works horizontally (so you can get LEFT or RIGHT or any numerical value 
inbetween or even further left or right) and for other objects
the direction property works vertically (so you can get UP or DOWN).

Note that, internally, both #LEFT and #DOWN are shorthands for the 
numerical value -1.0 and similarly, #UP = #RIGHT = 1.0, so you if you 
want to confuse the reader of your .ly file, you can for example use
\override BarNumber #'direction = #LEFT
which will result in bar numbers placed below the score lines.

Note also that for technical reasons we cannot have different
versions of the documentation texts of the direction property
for different objects, even though it would be more pedagogical
to only mention #UP and #DOWN for objects where that's relevant
and #LEFT and #RIGHT for the rest.
