This is quite annoying! I'm using 13.10 and I just tried to safely remove a Samsung 1TB external drive (USB3.0 device plugged into USB3.0 port) but it kept remounting. I tried it this way as well:
sudo udisks --unmount /dev/sde1 sudo udisks --detach /dev/sde1 and that also remounted except it took a few seconds longer.

I have noticed that similar already happened with a very old Ubuntu version - Bug #110589 and as that is so long time ago I thought it is better to open a new bug. Reason of the problem might even be completely different.
