While Jiim is 100% correct, I would suggest that you ignore the reference to Law 23 unless it really looks as though the non-offenders have gained from their offence. Then you might have a quick look at it, but it is a very rare occurrence.
However, the main thing I wanted to mention was that you said
South explains to TD that she thought E was going to bid.
I trust the TD made every effort to stop South explaining. It does not affect the ruling at all, and gives unauthorised information to partner. Players do try to tell the TD why they did something wrong, and part of the skill of the TD is silencing them when they do!
