In deuteration of aryl halides with CD3OD, beta deuteride elemination (C-D bond cleavge)is faster than weaker O-D bond? why ?

Compare to C-D bond O-D bond is weaker. According to catalytic cycle (attached below) O-D bond cleavage is not occur? Could please explain the reason? Reaction condition: Pd(OAc)2/ Catacxium...
