YES

Problem:
 f(s(x),y) -> f(x,s(x))
 f(x,s(y)) -> f(y,x)

Proof:
 Matrix Interpretation Processor: dim=1
  
  interpretation:
   [f](x0, x1) = 3x0 + 2x1 + 4,
   
   [s](x0) = 4x0 + 3
  orientation:
   f(s(x),y) = 12x + 2y + 13 >= 11x + 10 = f(x,s(x))
   
   f(x,s(y)) = 3x + 8y + 10 >= 2x + 3y + 4 = f(y,x)
