Yes, that is the case.

Why?  I see the same behavior on physical machines.  If I want to use a
usb stick after ejecting it I have to unplug and re-plug it.

Well, the guest owns the device.  When the guest sends a eject command
it will be forwarded to the device like any other request issued by the
guest ...
