I think the notion of "any moment" is not particularly applicable here...
Imagine a scene similar to one generated with Chris Colefax's City
Generator. The implication that Warp (probably; me -- certainly) meant is
that is if you, say, use different streams *and* different seeds for each
block, you may still end up with very similar blocks since the sub-sequences
your RNGs generate may still overlap.
To be even more specific: think about blocks with scattered trees. If your
streams' sub-sequences overlap, you may end up with many *equally* (not even
"similarly") shaped and located trees in different blocks. Hope you got the
idea...
