WRB both sides of sheathing – GreenBuildingAdvisor

Hey all, I was reading this older post about why we caulk between top plates: https://www.greenbuildingadvisor.com/question/why-caulk-between-studs-etc

It made me think about something tuff shed does (mostly because their name is plastered all over the wrb) on their detached garage builds – WRB on both sides of sheathing.

That older post indicated that a decent amount of air leakage gets in behind the studs. I assume this is probably the studs that are on top of a joint in the sheathing, which makes sense. However, if you have another WRB between the sheathing and studs, would it not help to substantially reduce air leakage? Has anyone tried this?
