No, the /dev/disc device is being used both times.

   geli attach disc

creates a disc.eli device.  Now create the label on *that*:

   glabel label 1213 /dev/disc.eli

Maybe some ASCII art will help:

   ,-disc--------------.
   |                   |
   |  ,-disc.eli----.  |
   |  |             |  |
   |  |  ,-1213--.  |  |
   |  |  |       |  |  |
   |  |  |       |  |  |
   |  |  `-------'  |  |
   |  |             |  |
   |  `-------------'  |
   |                   |
   `-------------------'

...well, maybe not.
