The grammar is less than perfectly clear, isn't it?  But that reading
just doesn't make any sense, because it would allow <table contents
source> to be (among other things) <table element list> <table element list>
which I am sure is not what they intend.  The last line has to be part
of the second alternative, it seems to me, and therefore the
next-to-last line is too.
