I fail to see an example in the proposal (other than a layout of the dominoes as played, which I do not consider to be a plain text use) where there is a semantic distinction between orientations. There are examples in Figures 4 and 5 where an orientation has been chosen for stylistic reasons. However, those stylistic reasons can be accommodated without having to encode all four orientations of each bone, by picking a standard orientation for the unstyled bone.
