VPD explained in an OSU Extension Fact Sheet: http://ohioline.osu.edu/aex-fact/0804.html
I feel like being a troll this morning so I'll say I don't buy it. I'm vegging in a Seattle basement and have 42RH with 70F below plant level. I'm not going to add moisture to get out of the Red Zone and it's raining right now.
2nd edit: I guess the VPD really applies in a greenhouse or tent.
