If you have two separate bindings, you need to link them in your
implementation. If the primary binding cache entry (I consider the one
for the IPv6 home address as the primary one) is removed, the IPv4 home
address binding cache entry should also be removed.

Currently we don't support a scenario where the mobile node can delete
the binding cache entry for the IPv6 home address, but keep the one for
the IPv4 home address.
