This is probably the configuration for the domestic 777s that will be reconfigured soon.
"Ten international 777-200 aircraft that currently have eight United Global First, 40 United BusinessFirst and 218 United Economy seats for a total of 266 will be converted to the new 77G subfleet with 28 lie-flat seats, 102 Economy Plus and 234 United Economy seats for a total of 364. The other nine aircraft to be modified are currently in a domestic configuration of 32 recliner-style United First seats and 312 United Economy seats"
