That statement refers to Ogham, not Mongolian!

Ogham carved on stone is read up one side of the stone, then (if
necessary) across the top of the stone, then (if necessary) down the
other side of the stone.  Now maybe it's just a mistake to assimilate
this scheme to any kind of two-dimensional layout, since all known
instances of Ogham on manuscript are ordinary horizontal L2R, like Latin
(with which it is most often mixed).

The difficulty arises when Ogham is mixed with vertical Han or with
Mongolian, since once the basic directionality becomes vertical, the
tendency to read the Ogham BTT will become automatic.  This is analogous
to the problem that fantasai has pointed out with Latin script written
in lr progression when Han gets mixed in: the normal reading direction
of lr-Latin is BTT, but any Han included will automatically be read TTB,
corrupting it.

*sigh*

One of my favorite lines in the Unicode Standard reads:  "There simply
is no traditional Japanese method of typesetting Devanagari."
