I can easily imagine situations where a ball is 100% seen to enter a penalty area but not seen to exit it (ball skips on the water or hits rock just under the surface and flies off etc)
So for sure it’d be known or virtually certain it went in to the penalty area and at the same time the player can have no knowledge that it exited the penalty area
Wouldn’t the player be correct in taking the drop at point of entry even if they subsequently found the original ball on the far bank after a new ball was put into play?
Yes. See Rule 17.1c.
As mentioned above, the original ball is out of play and would be a wrong ball if a stroke was made at it..
