I would have to disagree here as (technically) our trade has to be one of the hardest trades to understand and learn. Designing a specific electrical circuit requires a lot of knowledge to be done properly. Working in a commercial environment on site we have everything designed for us and work from drawings but that is far from easy understanding and interpreting the drawing to produce the finished product to the required spec. Working out what others have done comes with experience and a good understanding of testing and inspection to work out what our test results mean. You have asked in your post if there is any reason a shower with a pull cord isolator would be fed by two supplies and experience should of told you this would not be the case and it needs urgent investigation. On the plus side you have found that it was supplying a circuit which was not correctly designed and installed and you have rectified the issue.
Hopefully your assessment goes well and you have learnt from this as in my experience every domestic property is different from another.
