DataPump on RAC servers changes the group ownership of dump files to ASMADMIN so the application DBA cannot move the dump files.

Oracle GRID installed as orainst ID.
Primary group is oinstall.

Oracle rdbms installed as oradba ID.
Primary group is oinstall

uid=29975(orainst) gid=4185(oinstall) groups=111(asmadmin),112(asmdba),113(asmoper),716(dba)

prms006a> id
uid=29976(oradba) gid=4185(oinstall) groups=110(oper),111(asmadmin),112(asmdba),716(dba),5431(dpwd),5434(localbin)

GRID and RDBMS is installed by one group and DataPump is being run by another group. Ownership of the dump files is orainst. Without the group ownership being oinstall or dba (accessible to both groups), the application DBA cannot move the dump files.
