What does "Door name - reverse definition" mean?

edit

Hi..

I have a question about modelling internal doors in Energy Plus (V 9.6). I exported the Heating Design Energy Plus file from Design Builder ( V 7.0.0.096). I draw one door inside the building that connects hallway to main bedroom. In Energy Plus IDF, I get the following FenestrationSurface:Detailed object.

! Door, 1.999m2

FenestrationSurface:Detailed, SecondFloor:Unit8XMBR_Partition_4_0_0_0_0_0_Door,  !- Door name
Door, Project internal door,             !- Class and Construction Name
SecondFloor:Unit8XMBR_Partition_4_0_0,   !- Base surface
SecondFloor:Unit8XHallway_Partition_2_0_0_0_0_0_Door_10061,  !- Corresponding other surface
0,                                       !- View Factor to Ground
,                                        !- Frame divider name
1,                                       !- Multiplier
4,                                       !- Number vertices
1.9711583543,-29.96357673, 2.64795,     !- Vertex 1
1.9711583543,-30.96332073, 2.64795,     !- Vertex 2
1.9711583543,-30.96332073, 4.647438,    !- Vertex 3
1.9711583543,-29.96357673, 4.647438;    !- Vertex 4

However, I get another FenestrationSuface:Detailed object as below:

 ! Door, 1.999m2

  FenestrationSurface:Detailed, SecondFloor:Unit8XHallway_Partition_2_0_0_0_0_0_Door_10061,  !- Door name - reverse definition
     Door, Project internal door_Rev,         !- Class and Construction Name
     SecondFloor:Unit8XHallway_Partition_2_0_10059,  !- Base surface
     SecondFloor:Unit8XMBR_Partition_4_0_0_0_0_0_Door,  !- Corresponding other door subsurface
     0,                                       !- View Factor to Ground
     ,                                        !- Frame divider name
     1,                                       !- Multiplier
     4,                                       !- Number vertices
      1.9711583543,-30.96332073, 2.64795,     !- Vertex 1
      1.9711583543,-29.96357673, 2.64795,     !- Vertex 2
      1.9711583543,-29.96357673, 4.647438,    !- Vertex 3
      1.9711583543,-30.96332073, 4.647438;    !- Vertex 4

The second one is referred to as 'reverse definition'.

My question is: Are these two same doors? If I create a natural ventilation model and set one of them as "OPEN", will the door with reverse definition open too?

Thanks.
