Google Chrome’s setting/option icon a variation of the hamburger menu?

I noticed on a recent Google Chrome update that the setting/option icon changed from the wrench to three dots, which I thought was interesting as this seemed to related to the 'more' symbol but turned into a vertical version or an abbreviated form of the hamburger menu where the three stripes are shortened to three dots.

Are there any examples where such an icon has been used for a similar purpose, or have the people at Google simply come up with something that they think the users will understand?
