Thanks for the explanation. I've never made documents with more than one
author, so I've never thought about this scenario. For a moment I
thought org supported more than one author (explicitly, I mean).

Anyway, \and is just a formatting command: add a space between two
authors. Some people may prefer to put a line break \\ or anything else.
Of course, \and (and any other format command) will have a negative
effect on the pdfauthor metadata, which only collects text strings. It
is a similar problem to the one with footnotes, which Maxim commented
on. I think the basic problem is that org uses #+author, #+title, etc.
as a single source for both the metadata strings and the exported
format, i.e. the title, the author, the date that is printed somewhere.

Perhaps the ideal would be to distinguish in some way between
author-metadata and author-exported-format. For example something like:

#+AUTHOR[John Doe and Luke Skywalker]: John Doe @@latex:\and@@ Luke
Skywalker

The optional string in square brackets would be the metadata; the rest
would be the direct exported format. If there is no optional string, the
value is used for both metadata and format. Could this be also a
possible solution to the footnote problem?
