The double-up and -down are there, there's just a turn in between them "double" part. At least, that's what it looks like to me. Sort of a stretch calling them that, but probably technically OK.
Though I do have to agree; the layout looks kinda short. I wish it was longer; maybe a nice helix in the middle of it? Eh, whatever. Looks like an awesome ride. The first drop is UGLY, though...
