With https over VPN, at least the vpn provider cannot inspect the contents of your traffic. With a browser running on a remote machine, whoever controlls that machine can. This is better than VPN only in a scenario when you either controll that machine or fully trust the provider

I assumed it was more for security than privacy. Run the Javascript remotely so your own machine will be (or at least, is more likely to be) be protected from zero-days.
