Inasmuch as "catholic" implies that all EO Churches practice and preach the same theology, as they have since the Church was established. In that aspect "still" is meaningless, because EO Churches never stopped being catholic.

There is one reality in Christ not two
No, there are two realities to Christ -- human and divine. There is also no such thing as "Christianity" as a homogeneous religion. The only thing Christians agree on are the three persons of the Holy Trinity; everything else is subject to schismatic fallout, which started in the East, was checked, but resurfaced in the West and continues to this day.
