cifs_mount.sh: SINGLE_CIFS_CONNECTION=false with LOCAL_DIR list

cifs_mount.ini:

SHARE="mister/games"
LOCAL_DIR="NeoGeo-CD|PSX"
SINGLE_CIFS_CONNECTION="false"
BASE_PATH="/media/fat/games"
MOUNT_AT_BOOT="false"

Using a RetroNAS where I only want to mount and use a couple games directories to override those on the MiSTerFPGA SD card (in the above example, NeoGeo-CD and PSX).

If SINGLE_CIFS_CONNECTION="true", those two specific game directories are binded correctly, and with //retrosmb/mister/games/ mounted to /tmp/cifs_mount.

However, if I set SINGLE_CIFS_CONNECTION="false", I see the following:

Shouldn't the result be the same as with SINGLE_CIFS_CONNECTION="true"?

Start with cifs_mount.sh and the cifs_mount.ini settings shown in the report. Reproduce both SINGLE_CIFS_CONNECTION modes with LOCAL_DIR set to NeoGeo-CD|PSX, then compare the resulting mounts and directory contents. Done means the false mode mounts only the requested directories with the same visible contents as the true mode.
