Doesn't recall actually use the values and re-writes them to the brain? I seem to recall that being why we can have new associations and why memories can be slightly altered or degrade every recall.
If that were the case, you wouldn't just remember things a little wrong, you'd try and recall your name and instead be remembering a field trip you took in 3rd grade.
The other guy is right. Pass by value is a better analogue, and the act of recall actually performs a mutation.
