A burned or dirty connection there or bad neutral could cause power to
seek the path of least resistance back to ground, your metal siding.

If his neutral connection was so bad that going through siding and him was
the best path, then he would certainly notice that the lights were not very
bright!

It clearly was not the best path: he's still alive to ask questions.

Equally clearly, there was an alternative path; otherwise, none of the lights
would have worked at all unless someone was standing there touching the
siding.

It doesn't have to be the *best* path to get a shock off of it. It just has to
be *a* path.
