The book is clear on this, but when using the revised flying rules it can be played that way. Some of this "reach" business was going to be addressed before EE went under.
Wedge does know the rules, and I always defer to him. I think the rule in the book keeps flyers from being too powerful, but we've been playing with the Demon Wings being able to strike from reach, as can a ground troop attacking another troop on the ground using a spear or polearm. They move to within 1", strike from reach with NO charge bonus, if the model survives, it may try to use its Wait counter to charge back.
All this is coming from playing with Talamini, and should be taken with a grain of salt.
