Fascinating! I did not consider this edge case! An alternative implementation would be to change InternalGeoLine.reduce to not make the decision on non-overlapping based on it's own state, but on the state of all geo-lines being merged. We should only merge as non-overlapping if all geo-lines are non-overlapping. That would be a change to a single method.
This reverts commit 530e1216b26216d2228285ab205b9db37b3aeddb.

We are currently creating empty geo_line with the flag non_overlapping equal to true which is causing issues when the driving geo_line for merging is this empty object. This PR make sure that empty geo_lines are created with the right flag.
