Oooo...that's different and starts to get fuzzy. It doesn't differentiate multi-hull course vs. monohull course / long vs. short. It just says for Flying Scot, Windmill, 420, mutihulls "Short Weather Mark - Red" and "Long Weather Mark - Yellow". In my opinion, the SI's fall short of defining what the long and short marks are and how they'll be used. The interpretation is left up to something that would apparently be vocalized in the skippers meeting...i.e., you can't tell which marks you should sail around if you are a multihull just from reading the SIs....or there could have been some amendment posted to the notice board (which would have been the way to handle it if caught at that time).

In this case, if I was told to sail the "Long course" (and actually read the SI's for a change), I would probably sail to the color of the mark and ignore the positioning of it relative to the other mark. There's nothing that says the long course will be outside the short course or how they relate to each other - only what color it is. "Long" and "short" really don't mean anything in this context other than the name of the course because they're not defined with any relationship to the other.
