Probably...
There are various quotes knocking around about that session, so maybe there is a modicum of truth in there somewhere.
Here is another one:
"If I can remember this right, the story behind this one (from Carol Kaye) is that the drummer on the session was playing too far behind and kind of dopey. The producer asked her to play something really forward and 'up' to pep up the drummer, and that's what she did.
She didn't think they'd keep the take on the track, let alone that it would become a minor hit, as she thought the line was too busy..."
