In short you can determine caching granularity with this information. For
instance, cache="true" on a group can try to cache individual element
renderings (say tesselations if I am using OpenGL to render it), so it is
still easy to rerender the group if some elements move around or change
(since cache="true" does not imply that elements in the group would not
change). On the other hand, static="true" could cache the group as rendered
offscreen ("texture" in OpenGL terms) and simply rerender that offscreen
from scratch every time something changes.
