Even though L2 has a relatively small signal across it, it can still 'pick up' radiated fields and limit its effectiveness. I once had a situation in a LCLCLC filter for a phono stage where the ripple at L2 and L3 was the same rendering the last filter stage ineffective. As it turns out L3 was picking up radiated fields from L1 and a 90° rotate of L3 made the earth flat again.
