Judging from:

%%%
\directlua{%
local dir = {"T", "B", "R", "L"}
local dirnode = node.new(8, 7)
for _, a in ipairs(dir) do
  for _, b in ipairs(dir) do
    for _, c in ipairs(dir) do
      tex.print("\noexpand\\bodydir " .. a .. b .. c)
    end
  end
end
}
\bye
%%%

tested with 0.71, rev 4358, that seems to be the case.

Best,
