In my case, I had the initial two year Thai license that was issued easily when I showed them my valid US license.
I didn't pay attention and my Thai license expired more than a year before I went to renew it.
In this scenario I would have to waste most of a day sitting through those boring videos to renew my license. They told me I couldn't use my still valid US license as a shortcut to getting my Thai license re-issued. I believe that is what the sentence I quoted above is telling us.
