If someone says they have a disorder that isn’t Tourette’s but is a bit like Tourette’s I just can’t fathom why someone with no other knowledge of the situation would be intent on somehow “proving them wrong” and establishing that it is Tourette’s. The link you posted establishes that Tourette’s is a tic disorder. The person says they have a tic disorder that isn’t Tourette’s. I’m perfectly happy to take them at their word about that.
