Even though these two atoms are interacting with each other, their dipoles may still fluctuate. However, they must fluctuate in synchrony in order to maintain their dipoles and stay interacted with each other. Result of synchronizing fluctuation of dipoles:

Dispersion or London forces are large networks of intermolecular forces between nonpolar and non-charged molecules and atoms (i.e. alkanes, noble gases, and halogens).

Molecules that have induced dipoles may also induce neighbouring molecules to have dipole moments, so a large network of induced dipole-induced dipole interactions may exist.
