You are confusing device file with (mounted) file system.
You can't "cd" into a device file (/dev/sb1), only into
a directory, which is part of a mounted file system. Then,
this directory is "in use". But then you can't umount the
corresponding file system.

So either "udisksctl" is lying or something else is happening
behind the scenes (e.g. an over-eager automounter remounting
the file system again).

I'd watch the logs for more info.
