To me it is useful each time multiple post-build scripts are used, 
because is
makes it easy to understand what's happening and which scripts you are 
running
(and which you are not running).
E.g., I have multiple products with a common base, plus some "optional" 
features.
Some features needs a specific post-build script. Each product 
implements a subset
of the features, but these subsets overlap between different products.
When a build a product's rootfs it is useful to see if I am running all 
and only
the correct post-build scripts: the "common base" script, plus the 
scripts for the
wanted features.

Of course I agree this change should be done also in the post-image scripts.
I will submit a patchset that does also this.
