I was working the handoff position at the sector. There was a lot of weather deviations and route closures. Aircraft X had a flight plan which took them backwards. The pilot did not question the route and I did not catch the fact that the routing took them backwards. Aircraft X was coordinated with the adjacent sector who also did not catch that the routing would take this flight backwards. ATOP probed the flight as if he was going reverse course at a fix. The flight did not reverse course and came together with another flight at 41000 feet.ATOP should have a logic check when a flight reverses course like this. Also the pilot didn't fly flight plan.
ZNY Center Controller reported the flight plan processing software did not detect that an aircraft filed a route which reversed course at a fix.
