I believe they use different versions on different laptops. I think if you check in the readme file that comes with the updater driver, you can read which version is the latest for each laptop.
I had the same question about 3 days ago when I updated my son's laptop Turbo Gear on his G752VT and it updated to a different (earlier, like you) version than on my G752VY. I searched for that same information and found it in one of those text files in the driver.
