Here's how I read it...
The statement appears to differentiate communion between the apostate and the orthodox within TEC. The official hierarchy and TEC overall are in impaired communion, however, the orthodox within TEC who do not support the official TEC position can still be in full communion with the Tanzian church on a diocesan, parish or individual level.
Huber is correct, albeit without defining "impaired." I am guessing that we might all be agreed on this (at least until TEC comes forth with some statement that blows all this away...).
