NO

Problem:
 a(b(b(x1))) -> b(b(a(a(x1))))
 a(a(x1)) -> b(x1)

Proof:
 String Reversal Processor:
  b(b(a(x1))) -> a(a(b(b(x1))))
  a(a(x1)) -> b(x1)
  Unfolding Processor:
   loop length: 6
   terms:
    b(b(a(a(a(a(x1138))))))
    a(a(b(b(a(a(a(x1138)))))))
    b(b(b(a(a(a(x1138))))))
    b(a(a(b(b(a(a(x1138)))))))
    b(b(b(b(a(a(x1138))))))
    b(b(a(a(b(b(a(x1138)))))))
   context: []
   substitution:
    x1138 -> b(b(x1138))
