I believe the water in the hoses can flow in either direction so if the connections fit better one way and do not leak, then it should be OK to install them as needed. The fill rate on any washing machine is more closely related to the water pressure in your location, the machine you are using, etc. Most if not all washing machine hoses are of the same size ID and should not affect the flow rate either way.
I don't see that it would make a difference other than wall clearance. You just don't want to crimp the hose.
Basically, there is nothing different about the connector ends...As far as the size goes. As a result, they would fit any washer with "standard" connection fittings.
Maximum temperature rating is 140 degrees F.
