Read/write access for linked github accounts

I want to link my github account for automated builds. This brings up two options. First is the recommended option, which gives dockerhub read and write access to basically any repo (public or private) under your github account. Second is the limited access option where you only let dockerhub to have read only access for public repos. I choose the second option for being safe. However, even when you select this option, docker hub page shows read/write access on the description of the linked account. Is this just a mistake in the description or are we granting any write access to docker hub?
