[ANSTHRLD] conflit question

[Hedwig]

(filedless) a bear's head cabossed/caboshed argent

would that conflit with:

(filedless) a bear's head cabossed/caboshed purpure
Or does it have 2 CDs?  Other than the two instances here I can find no
other conflicts...but then I haven't finished my tea yet either.
Also, if a person is granted permission to conflict their device with
someone else's device do you then need to get another letter of permission
for a badge?

I.E.
Ursula Messerschmitt<http://oanda.sca.org/cgi-bin/oanda_name.cgi?p=Ursula%20Messerschmitt>

   - The following device associated with this name was registered in May
   of 1998 (via
Caid)<http://oanda.sca.org/cgi-bin/oanda_date.cgi?y1=1998&m1=May&y2=1998&m2=May&kC=checked>
   :
   *Vert, a bear's head cabossed argent.*

granted Gunthar Waldmann permission to conflict :
Ber bend sinsiter vert and sable and bear's head cabossed argent

So does he then need another letter from her to try and register his
proposed badge:
(fieldless) a bear's head cabossed argent

Any help?
