I have my own false memory from seeing ESB in a 1981 re-release. When Luke is in the Wampa cave, I have a distinct memory of Obi Wan telling him to use the force telepathically to lift the lightsaber.
When the VHS of ESB came out, I was shocked that Obi Wan’s voice was absent from that scene. I think when I first joined this forum it was one of the first things I asked about. At this point I don’t think that voice over existed but I don’t know how I came up with that as a kid. Unless those re-release prints had some weird meddling by Ben Burtt that is now forgotten in time.
This was in the script exactly the same as you put it.
It is possible that the voice over exists although I never heard it or remember it
