Yes, but the AM has lighter tapered stanchions, a lighter crown, and in the 6" travel setting it's going to be a good deal flexier than a DJ or Z1. It's a great 5" travel all-mountain fork that is a good deal lighter than a Z1, and it's nice to extend it to 6" for the ocassional nasty downhill on a ride, but it's no Z1 or DJ.
You're right they don't call it the "XC1", but on the sticker that comes with the fork it says that you shouldn't use it for "DJ" and "freeride".
Your assessment is not far off or anything, but as a bike mechanic and salesperson red flags go off when I see someone say "I want an AM1 for some DJ and Freeride". If you say that you want it for mostly XC and trail use, and will only occsionally shuttle with it and not drop off of every big drop and such, then ok, but when you just say "DJ and freeride" I'd err on the side of caution and recommend a Z1 or DJ fork.
