Still don't know what to make of it. But it doesn't really matter much, anyway.
Ovi, it doesn't matter much today
, but you brought up an important historical point.
I believe Bob Dylan wrote 4th Time Around before the Blonde On Blonde recording sessions began on October 5, 1965.
The Beatles recorded Norwegian Wood October 12-21, 1965.
So the key event was when this meeting of The Beatles and Bob Dylan took place and who showed who what. I guess we'll never know for sure. It's interesting to read what John Lennon said in his interviews and what Al Kooper said in the video you posted.
I wonder what Bob Dylan remembers.
