IMHO fogging is for increasing humidity without the need to flood the cage multiple times a day. When some of these techniques got started we didn't have the luxury of auto misting systems designed for small scale enclosures so trying to keep a cage humid in dry conditions meant many spray sessions each day. The result was waterlogged plants, cage structures, furniture, etc. Its a quick way to saturate the air without creating a swamp. I have had montane species just sit in the fog enjoying it. Others not so much. Spraying or misting is more to provide drinking/eye-cleaning. If you've ever been in tropical forests you would see that there are lots of fogs and almost visible mists at some hours of the day. The chams could sit and absorb the moisture just by breathing. And, as the entire forest is humid, there is airflow from breezes.
