Based on usage of filtering for a URLs where a segment equals a value, it looks like the path segment # is being ignored. Based on results it looks like it is finding urls where the value is in any of the path segments not the specific positioned one.
I actually cannot replicate this, and the tests pass. Going to write this off as bad data/something not tagged properly in the affected implementation. If this comes up or is replicatable, will open a ticket then.
