I looked at a couple other photos from the evening where his tie is more clear and the position of the yellow and red stripes appears to be reversed compared to the Arygll and Sutherland Highlanders tie.
Maybe the pattern just appears upside down? I have a tie that's made that way. As you can see below, the pattern is the same as the example you showed, but it is just upside down. I'm guessing perhaps there's not much attention paid to the directionality of the pattern amongst tie makers?



I also notice that the VC's tie seems to have the blue and green stripes the same width, where they appear to be different widths in your example. Curious!
