Auto mount point remains until manual deletion

[Andreas]

I am facing the following issue:

The device I'm working on is often turned off through a cut in power (Embedded device). Ext4-formatted usb drives which all have the same label may be connected to it (though only one at a time). So much for the setup.

After a new start following a power cut, occasionally (not always, but still easily reproducible) the mount point (e.g. /media/username/label) remains, independent of the connected drives.
On subsequent mounts of the usb device (or any usb drive with the same label), the label is enumerated (label1 etc.).
Only after manually deleting the mount point and rebooting (e.g. rmdir /media/username/label) do the usb drives get mounted with the original label again, as before.

I am using Ubuntu 14.04.2 LTS.

I believe this is expected behaviour, not a bug. But I'm no expert in udisks2.
