I assume you probably got that part number from the fred beans website Legacy2012. It is odd how they show a "*" instead of a "1" or a "0", maybe because they offer both SOA868V9240 and SOA868V9241 fluids, but I'm not sure. They have both the older stuff pictured in the white bottle, and the newer HP stuff in the silver bottle.
Like N.sane said, SOA868V9241 is the stuff you want, the ATF HP.
It looks like SOA868V9240 is Subaru's older Dexron III stuff.
When I go to the fred beans site, and click "check price" for the ATF, it does display the part number you want "SOA868V9241".
I'm also assuming that you still have the 2009 legacy with the 4eat, as show in the link below. If you do have a newer legacy, that might change things.
