I once visited a doctors office that wanted me to sign a HIPAA release form to release my health records to... myself!
If you find out that your records were released three times in the past year and when you ask to whom they were released to, it's better to have a piece of paper with a signature on it than for them to say "it must have been you, because we don't have any paperwork".
Now the coversheet for the exam has a place to write your name and sign it which you must do before starting the test.
The older brother signed it as his younger brother. Then was charged with forgery. The requirement to sign was there to make that kind of cheating a crime.

It makes sense why (default to release to nobody but the patient), but I just thought it was funny that although she has the authority to add herself or anyone else that she wasn't on the list by default.
I honestly would rather have this.
