Hmm... which is it?

I'm not sure I understand your question. I could have written:
(error "Sequence %s cannot be empty" sequence)
but I thought it was useless because SEQUENCE is empty and nothing
meaningful would be added to the message.

The question was: should I obey the docstring or the code?

The code, always the code.
Indeed, pretty consistent, after all this function is about getting a
_random_ element from a sequence; if the doc string assures something
opposite as the code, then it's very hard to predict the result of the
coin flipping experiment, regardless of which is the underline random
generation engine.
