Something that openly defies Catholic dogma (like everything this synod is about) cannot be infallible.
But that's not what I'm asking. Are synods considered part of the Ordinary Magisterium? If so, then we should expect to get infallible teaching/teaching that does not defy Catholic dogma. If we don't, then that's a whole different story (like Vatican II).
Put another way, under normal circuмstances (say before Vatican II) would a Synod like this be considered OM?
This is what I could find on the internet...
The nonuniversal ordinary magisterium may also be exercised by groups of bishops, such as a national conference of bishops or an international gathering of bishops, such as a synod. Again, teachings from such groups of bishops would apply only to those Catholics under their authority. Lastly, the pope, who also holds the title Bishop of Rome, may in his secondary capacity provide a teaching that is not applicable to the universal church but only his diocese.

The infallibility of the Church is confined to the formulation of truths in question. This infallibility is not wholly a God-inspired energy which would affect the participants of the synod to such an extent that they would be inspired to pronounce all the truths at one time as a whole system of a Christian catechism. The Synod does not formulate a system of beliefs encompassing all Christian teachings and truths, but only endeavors to define the particular disputed truth which was misunderstood and misinterpreted. The Church of Christ and its divine nature, as set forth above, is the foundation upon which the Eastern Orthodox Church [sic.] continues to administer and nourish its faithful, thereby protecting its fundamental essentials." Rev. George Mastrantonis, of the Greek Orthodox Archdiocese of America.
