Don't worry, Bob Caputo submitted a proposal to eliminate the fitting/drop loophole for the next edition, so at least it will be clarified going forward.
My issue is with the wording in the handbook. They say 'handling of the sprinkler during removal' which leads me to believe if you never touch the head, and treat the fitting/drop carefully, it should be fine. Then they go on to talk about damage to the water seal and/or seat (my best guess is due to torque from wrenching) and don't talk about the treatment of the head, like throwing it in a bucket, etc. I think they could have worded this better or more strongly. I will be interesting to see what the TC says in regards to Mr. Caputo's proposed changes.
