Correct.  Within the metro area.  That is, as has been documented many

1) Cross the trust threshhold in the wrong direction.
2) Cross the cost-of-transit threshhold in the wrong direction.
3) Increase shared costs until conditions 1 and/or 2 are met.

al MAE-East-FDDI, which I guess would be a fourth case, but rare.
