Topologically, it doesn't matter whether the line is a zig-zag, squiggly or straight, as long as it doesn't divide the plane into multiple regions. In practical terms, even if they were on a circle, but one with radius about twice longer than their total length, the first worm would still say "two worms BEHIND me", because they'd be too far in the other direction.

Is this still hypothetical or are we discussing a real situation :)
