I have heard of Les Pauls with a bolt on neck, never seen one though.
As far as the jargon goes, we are basically just bickering about the advantages of different kinds of guitar construction. The neck can bolted on to the body like on Fenders, this is probably the most common way of doing it. The handy thing about this is that if you fuck up your neck, it's easy to replace. As far as wether you get more brightness and attack with a bolt on neck, I dont know. I find it had more to do with the wood used. A maple fingerboard brighter than a rosewood fingerboard. Single coil pickups also have a bright thin sound.
