The use case is the same as in the previous email, specifically:

Some widgets want to behave differently depending on the context in
which they are embedded.  For example, a payment widget might want to
send the user to a confirmation page for most web sites but might be
confortable with a more streamlined user experience when embedded on a
whitelist of sites with which they have a contractual relationship.

The payment widget might care about all of its ancestors.  For
example, suppose the payment operator has a relationship with
store.example.com.  They might wish to fall back to using a
confirmation page if store.example.com is embedded as a frame in
another web site (e.g., pintrest).
