Following screenshot is taken from Sipser's book:

This Turing Machine accepts  the language L = {w#w | w ∈ {0, 1}*}, my doubt is, what is the need of keeping transition for 0 and 1 on the state q6, if it is x->L in place 0, 1, x -> L on state q6 then also this machine is correct.  

Am I missing something
