Nope, that's pretty much it.
Although......
We are dealing with the Japanese arts here, and the single term used by one system may mean something completely different in another. For example, Nagamaki refers to different things in different systems, within Toda-ha Buko Ryu it refers to a weapon pretty much identical to a Bisento (from the Kukishinden Ryu).
With a mogito, the term literally means "imitation sword", and most typically means a steel-bladed unsharpened weapon, although certain schools refer to bokken with wooden scabbards as such (as Sukerin mentioned on another thread recently, I think). Still others refer to weapons not made in a "traditional" fashion, although they can still be sharp. Think of the mass-produced, oil-cooled lumps of steel for WWII in this fashion, or the common "wall-hanger" type items.
But by far and away, the most common meaning is an unsharpened steel blade. The other thing to remember, though, is that outside of practitioners, this is not a common term at all, and there are manufacturers who make Mogito and simply label them as Iaito for less confusion in the marketplace. They will typically state that such a weapon can be sharpened if needed, though, and that will be your big clue. A good example of this is Furuyama, who can be purchased through
