[Star Wars] Why is gravity sideways in the Death Star?

When the Millennium Falcon escapes it flies parallel to the hangar bay floor that everyone is walking on, but it emerges perpendicular to the surface.

The gravity on the Death Star appears not to be towards the center of the mass as it would be if it were a planet - it's sideways like it's a star destroyer that just happens to be spherical.

What's the purpose of this layout?  Does the gravity flip halfway down so that it's in the direction of a single plane that bisects the sphere?  Or is it unidirectional all the way down?

Artificial gravity. The Death Star doesn't have anywhere near enough mass to have an effective gravitational pull. I'd say less than 0.01Gs. 

Having the gravity constantly going towards the bottom of the station allows for far more space, as well as makes logistics infinitely easier. If the gravity was aligned so that it always goes to the core, the closer to the core you get the more curved the decks have to be. Making it confusing to crewmembers, not to mention difficult to move around. Turbolifts would have to circumnavigate the station, rather than just simply move through the core. Having gravity only act in one direction on the station makes everything a lot easier.
