bidi or multi algorithm?

Is Unicode's so-called "bidi algorithm" really bidirectional, that is, does it govern horizontal text layout in right-to-left and left-to-right languages?

Or is "bidi" a metaphor here, for more possible text orientations, including vertical boustrophedons and other historically available options? I'm asking because I tried to read the Unicode 3.0 paper documentation and wasn't sure what it was saying at some points.

Also, on the Internet, are historically vertically placed languages being written vertically? Some of them are BOTH vertical and right to left...........How difficult is this technically?
