While your location can absolutely still be tracked (via WiFi, Cell Towers, etc), disabling GPS significantly reduces the accuracy of this tracking, and disabling location history makes it even more difficult to freely track you.
While it's certainly possible Google maintains location history even after you opt out, doing so would likely be illegal, would possibly invalidate any data obtained from a warrant, and would unquestionably be a PR fiasco for Google when it got out.
As far as I'm aware, there's no evidence that GPS continues to function after turning off the software kill switch.
