Those are two distinct things: screen size bucket 
(small/normal/large/xlarge) vs. screen pixels per inch density 
(ldpi/mdpi/hdpi/xhdpi).


drawable-xhdpi is for images at 320dpi. If your tablet has 160dpi (a 
typical 1280x800, 10 tablet), Android will take the xhdpi images 
(lacking others) and scale them down by a factor of 160/320, that is, 
make them half the original size.


drawable-xlarge is for images at 160dpi, targeting xlarge screens. 
Running on a typical 1280x80 10 tablet, those don't need any resizing 
and are used as is.

Just to be clear, it may be transiently typical that a 1280x800 10 tablet
is mdpi, but it won't stay that way for long.

The *only* good reason I know of to use a screen size qualifier with a
drawable resource is if for some reason you want graphics to be slightly
bigger on a larger screen.  And for whatever reason you are doing that, you
should *always* still specify the density the drawable is for.

Actually, maybe it is time for aapt to start reporting errors if it is
given drawables that don't have a density qualifier.
