I was surprised to hear that, but I imagine it will continue to go on.
I have only heard about this intercommunion here on FR, so I have no independent confirmation of this, or any idea of the extent and specific nature of this intercommunion. It is of course not going to be publicized in official news releases, so FR may be as good a source of information as any.
It should be put in the context of the fact that not all Eastern Catholics are alike. The Melkites of Lebanon are easily the Eastern Catholics who are the closest (some would say virtually identical) to their Orthodox counterparts in doctrine and praxis of any Eastern Catholic church.
Even as regards the papacy, the Melkite patriarchs have been renowned for their de facto independence from Rome, and their persistent (some might say impertinent) demands at Vatican II were largely responsible for the sea-change in how the Vatican treats Eastern Catholics, at least officially.
