i haven't made every block yet to know that answer but right now it seems to be the symmetrical blocks and they fall into 2 categories.
1) the kind i just mentioned, they go together either way and the only difference is which fabric strip is on top. i think people mirror these because they will look exactly like the author drawing in the book but that doesn't mean they look like janes.
i don't think anyone has been allowed that close to the jane quilt - even some of the variations in DJ software say "it might be more like the original" but they're not sure either.
2) then there's some blocks that are symmetrical but if you don't mirror them the background fabric lands in the sections that should have the focal fabric.
now this isn't a tragic event but it might bother some people and they could make the block over to keep thing consistent through out the quilt.
off the top of my head an example of this would be M5.
