Ah, that's important indeed.  Thanks for spotting that!  Actually, the
main reason why tar checks for the same file being read twice is to
avoid recursive inclusion (e.g. "-T LIST1" appearing in LIST1 itself).

So perhaps tar should allow subsequent (as opposed to recursive) reads of
the same file?
