Does this man speak for the SSPX?

“What remains of the magisterium in the Church? It is a matter of faith that Our Lord endowed His Church with a living and perpetual Magisterium, that is to say a papal and episcopal voice which, in every era and at the present time, is the echo of divine revelation and the relay of tradition. Well, this magisterium, at least as regards the truths denied by the conciliar hierarchy, lies in Mgr Lefebvre in whom it can be found in a certain manner. He is the veritable echo of tradition, the faithful witness, the good shepherd whom simple sheep have been able to identify from the wolves in sheep’s clothing. Yes, the Church still has a living and perpetual magisterium and Mgr Lefebvre is its saviour. The indefectibility of the Church can be seen in the inflexibility of the Archbishop.”

Tissier de Mallarias, SSPX Bishop. Fideliter, 1989 (No. 72, p10)

My question: Archbishop Lefebvre is dead. Where is Mallarais' magisterium now?
