Please read my post carefully with understanding.

The p2p nature of transactions broadcasting

I am talking about rebroadcasting. And rebroadcasting logic behaves differently for cases:

  1. you are the owner of public key (even if only on receiving site)
  2. you are not the owner of public key

And any externally visible difference for those two cases can be leveraged to deanonymize users.

reasonable to say that the node that you see as the broadcaster to you of the transaction is not the creator of the transaction.

And that's why I pointed out the 'repeatable rebroadcast' part. Single measurements obviously won't reveal the owner. But repeated measurements over time will do it faster than you would expect.

How is rebroadcasting different from broadcasting in the p2p network? Can you point to some resources?

Never said it is different. Rebroadcasting means repeated broadcasting.

And the "repeating tx broadcasting forever (because of low feerate)" part is privacy compromising. Hope that helps clear things up. For more info just google "bitcoin rebroadcasting".
