It is in fact mind boggling that the Dalai Lama on the provisional level has seem to contradict the practice of a monk that he is suppose to be by issuing the ban and thus causing infinite amount of sufferings to the Sangha and the lay alike.
But in contemplating the Dharma we need to look at the definitive meaning of the teaching and in this case the "edict" of the Dalai Lama with regard to the ban. Definitive meaning is more subtle and most likely requires the interpretation of a qualified Guru.
In this case we then have the "Big Picture" interpretation for the reason of the ban with the motivation that the ban will in the end bring more benefit than suffering to sentient beings as a whole.
The interesting thing and also the most important thing is the individual interpretation of the ban depending on the individual's demographic ie who he is, what kind of background, educational (secular or spiritual), political if any, family, groups and economic motivations. All the factor of the demographics serve as a kind of spiritual filter that leads to the acceptance of the ban or not. We cannot rule of the "grays", the ones that on the outer level seems to accept the ban but on the inner level practice Guru Devotion and continue the practice. Still there seems to be an infinite types of people and motivations in the "grays" that are too complicated to totally discuss for now.
In summary whether the Dalai Lama is a Saint or not depends of what is your respond or reaction to the ban. How you act defines if he is a Saint or not.
