Mike,
I am not sure why it works, but, at least in my garden, it did. I had not heard the poison theory, just the electric shock. I"m not sure I'd call it a shock, rather a mild tingle, as it would have to work off of the electrical functions in the slug's body, which cannot be very much.
According to this site, it is a myth and they bust it.
Maybe it is taste. I'm not sure whether slugs have any sensory receptors in their slime covered foot, but apparently, thin strips of copper do not work. It takes a wider piece, such as the tape.
Beer definitely works, and that has to simply be drowning. At the time, using beer seemed like such a waste.
For those who won't mind an off-topic diversion, here is something I did in 2001 when I was messing with the copper tape stuff
