Correct, but it may be FDE+1 that needs discarding, not FDE.

We could even have FDE,FDE+1,FDE+2,FDE+3, where
FDE,FDE+1,FDE+2 all have initial_location == 0, and FDE+3 not.
We want to compare each of FDE,FDE+1,FDE+2 with FDE+3 for
overlap and discard those that do overlap,
not FDE with FDE+1 ; FDE+1 with FDE+2 ; FDE+2 with FDE+3.
