Most satellites i've seen had triples from the factory, of course with the appropriate FD. But, i think i recall seeing a compact double version a few years back. Either way, if you're using a double, either FD will work. The double FD, however, will not work properly with a triple.
Oh, and if you really don't care about matchiness and just want a double, pull of the right crankarm and remove the granny. Replace it, dial the limit screw to keep the chain from dropping inboard, and voila-- double crank for free.

I took a look at it, and I think it is the compact double FD you mentioned. the inner part has a straighter line down the front than the 2010 double pictured on the site, but it's nothing like the triple at all.
It's the older Satellite, so that makes sense.
