Wrong. That's exactly what was done. The hose you show is nothing like any hose originally intended for your car. Slant-6 cars did not come with V8 radiators, they came with slant-6 radiators, which have the inlet and outlet located appropriately for the slant-6 engine.
On your car, someone put in the wrong radiator and then dug around through a pile of hoses (or an illustrated buyer's guide) until he found a hose that would kinda work.
