According to my interpretation of the Jepp chart, DIYAD is formed by the
intersection of the HUO 094R and the LOC; or by the 13.5DME point on the

Yes. I get the same from reading the NOS chart, so at least we're both
on the same page.

But, what I don't understand is what value it is knowing that DIYAD is
13.5 DME from HUO. The only real reason DIYAD exists is to specify a
fixed distance out on the localizer course, and HUO DME doesn't help you
do that.
