Jerry, where do they nail through the starter strip?
Around here, they continue to nail at the adhesive strip which leaves the bottom of the strip to flap in the wind along with the top tabs.
Are there alternative installation instructions for your area?
I'm sure the manufacturer would have to provide documentation for any changes in their instructions.
Of course most of the shingles sold in "non high wind" regions could not be installed in the high wind regions, but for the rest of the country we still have the issue of installers making up their own rules.
