Exactly so. As I understand it, the Vermont plan was drinks in containers that weren't being refilled were going to be banned. So wash and reuse or you ain't selling that beer. :) Reused glass milk and pop bottles here in the UK didn't seem different in weight or thickness to non-returnable bottles of the same era. They've all got thinner over the years. The oldest milk bottles I can remember, from the 70s, were indeed quite chunky but they'd mostly gone by the 80s. No idea how long they'd been around though. The last fizzy pop refilling scheme I know of died about 5 years ago, leaving just a few dairies using it for milk.
