Question NMC passing through floor

NEC states that non-metallica cable passing through floor must be in conduit. Could someone please clarify? I will be running cable in 1st floor walls, through top plate, then bottom plate of upstairs bedroom. Does the protection from physical damage section require that I run the cable through a short length of PVC? I don't understand if conduit is needed inside walls, or only if wire is run through an exposed section of floor.

Cable inside a wall is considered protected from damage. The conduit protection is required if for whatever reason the floor penetration isn't inside a wall.

An example of the use of this rule would be wall mounting a box on a perimeter plaster-over-brick wall and the box is several inches off the floor. The cable is run through a hole in the floor that is outside the wall. The cable needs to be protected where it comes through the floor.
