Based on that limited video, I'd say your clutch is fine.
I am not a fan (haha no pun intended) of any spin test for a fan clutch. The fluid moves between chambers, so unless you know exactly what state it was in when it was shut off, there is no way to guess what it is going to feel like 10 hours later.
If your fan doesn't "roar" 100% of the time, then it is not locked up....and it is obvious that it is not too loose. Hence, it's probably not broken.
97 TJ Sport OPJ project (other peoples junk) I can't remember the last time I bought a new part.
