In some cases the aftermarket does that so they can use more generic end fittings where the factory had a special made end fitting. I my past experience, the new aftermarket p/s hose package would include a printed note stating something like, "Although this part may not appear identical to the OEM part it replaces, it will fit and function the same as OEM".
The hose currently in use on my 67 273 looks like what you have there. It's pump end is a little different.
That step section is strapped under the corner of the battery tray. No it don't look OEM but it works.
