Hi Tom!
The dropshadow effect layer would simply take the alpha mask of the
parent layer and apply the blur on that dynamically. So when in GIMP you
would have to recreate the dropshadow manually each time you draw on the
above layer, with a dynamic dropshadow effect layer, you would get that
done automatically.

Imagine you would create a set of filters applied on a layer - fill with
pattern with "keep transparency" on, apply displacement map based on
blurred copy of the alpha channel, applied bumpmap. And now imagine that
sequence being applied every time you paint on a layer automatically.

Hope that gives you an idea how layer effects can be useful.
