Don't forget the sun isn't the only light source that may be illuminating the lens - even of off frame. Car headlights, streetlights, reflected sunlight off glassy buildings. I don't think the direction of the sun really matters. If you're able to use the hood - use it!

Its still entirely possible to stray light unless you are taking photos in a completely non-light emitting environment - complete blackness
If there is light, there is some form of stray light that will be outside the frame being imaged, but that is still incident upon the lens and hence may cause some form of light artefact.
Quite simply, a hood greatly reduces the 'risk' of unimportant light falling on the lens and leaving some trace (e.g. flare, ghosting etc) and at the same time will likely improve the contrast of the image.
