Yes it goes to green zone as soon as you turn off to woodstone village (the zone change for the 36/78) but not going through burnmoor and fencehouses.

Perhaps people are getting confused as the T&W area ends at boundary house and restarts at the fencehouses rail crossing (hence the lack of nexus bus stop timetables) GNE allow network one tickets to travel through county Durham on this part of the route without paying extra
