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) = 6x0 + 4x1 + 6,
   
   [s](x0) = 4x0 + 2
  orientation:
   f(s(x),y) = 24x + 4y + 18 >= 22x + 14 = f(x,s(x))
   
   f(x,s(y)) = 6x + 16y + 14 >= 4x + 6y + 6 = f(y,x)
