Does macOS Safari use the same version of WebKit as iOS Safari (assuming the macOS and iOS Safari versions are equal)?

For example, does macOS Safari 10.2 use the same version of WebKit as iOS Safari 10.2?

I know that the WebKit revision number included in a release of Safari isn't publicly available, but if there's a WebKit bug that I know is fixed in macOS Safari 10.2 can I also assume that it's fixed in iOS Safari 10.2?
