My initial thoughts were the same... but the general tune of the fork is slower at the top and faster at the end. I was told that is the setup they found worked best with the Blackbox riders.
The slower starting rebound helps to keep the front end steady when pedaling and riding smooth rolling terrain and faster ending stroke helps recovery after big hits so you don't pack down in the travel. The example I mentioned from FR Cup #1 was a particularly fast rough section with a few big hits in, I felt like I was riding into the bars in that section, and in retrospect I think faster ending rebound would have kept me where I wanted to be in the travel - I am pretty sure I was getting stuck down in the travel there.
If you are riding something slower and steeper (the shore for example) you might want that slower so your front end doesn't kick back after infrequent big g-outs. However, at speed the fast recovery helps keep your bike steady. Think about it this way... you would neverrun out of travel on a bunch small stutter bumps, so why rush to get the fork back to the top? Whereas, a big nasty rock section that uses 80% of your travel on the first hit... you want to get back up to the top ASAP
it totally makes sense if you look at it like that. It be really cool to try one of those forks, can wait to get my hands on a pair
