Is sequence required for washing the feet if a person performing Ghusl only missed his feet before experiencing a minor ritual impurity (Hadath Asghar)?

Primary text

If a person washes his entire body except his feet, and then experiences a minor ritual impurity (like passing wind), sequence is obligatory for the three limbs (presumably hands and face) because they are affected by the minor impurity alone. Sequence is not required for the feet because they are affected by both the major impurity (residual from the partial Ghusl) and the minor impurity.
