I think he means the fact that Emergent has a straight shot 75XP path to FR+1 with usable talent in between and is by nature "cheaper" for being a universal tree.
By comparison FSEx and a lot of F&D trees make you dig through several other talents and have that out-of-career tax attached.
I never really understood that rationale though. Why take a talent tree unless you want the other talents provided? There are enough specializations that a few points here and there to get what you really want for your character isn't a bad thing.
FR is good, but its not the end of the world.
