If you look to the left side of the photo with the pipe boot you will see that the shingle with the nails exposed and the shingle above it have (what looks like to me) only a 2" offset. You can see the white nail lines and they are slightly different. The next shingle above that one looks like it is the correct offset. I would make sure the roofer nailed the shingles with the proper offset or it could void the warranty.
Most laminates call for a minimum 5 5/8" offset. That will really depend on your region though.
