Abount understanding join rules

Hello!

If I have this join settings below will both join conditions be executed or if the first one find a match in the MV will it stop and never tried  the second one.

In the "Configure Join and Projection Rules" I have set these two rules
Mapping Group   Action                                    Metaverse Object Type
1                         Join                                         PersonT
homeDir              Direct                                      uid
2                         Join                                        GroupT
homeDir              Rules extension avdelningsID     avdelningsID
