Just as it says. Do you want similar performance and characteristics in a fairway shaft, or are there differences for you?
For me I like a fairway wood shaft to be a little stouter throughout and probably slightly more tip stiff in particular, because I'm placing a premium on dispersion vs distance. Similar torque is good though, because then the shafts feel pretty similar. Weight I'm not too concerned about, but definitely not lighter than the driver shaft - the same or heavier, if anything.
