YES


Applying context closure of depth 1 in the following form: System R over Sigma
maps to { fold(xly) -> fold(xry) | l -> r in R, x,y in Sigma } over Sigma^2,
where fold(a_1,...,a_n) = (a_1,a_2)...(a_{n-1}a_{n})

Remains to prove termination of the 8-rule system
{ [a, a] [a, b] [b, b] [b, b] [b, a] [a, a] -> [a, a] ,
  [a, a] ->= [a, a] [a, b] [b, a] [a, a] ,
  [a, a] [a, b] [b, b] [b, b] [b, a] [a, b] -> [a, b] ,
  [a, b] ->= [a, a] [a, b] [b, a] [a, b] ,
  [b, a] [a, b] [b, b] [b, b] [b, a] [a, a] -> [b, a] ,
  [b, a] ->= [b, a] [a, b] [b, a] [a, a] ,
  [b, a] [a, b] [b, b] [b, b] [b, a] [a, b] -> [b, b] ,
  [b, b] ->= [b, a] [a, b] [b, a] [a, b] }



The system was filtered by the following matrix interpretation
of type E_J with J = {1,...,2} and dimension 2:

[a, a] is interpreted by
 /   \
| 1 0 |
| 0 1 |
 \   /
[a, b] is interpreted by
 /   \
| 1 0 |
| 0 1 |
 \   /
[b, b] is interpreted by
 /   \
| 1 1 |
| 0 1 |
 \   /
[b, a] is interpreted by
 /   \
| 1 0 |
| 0 1 |
 \   /

Remains to prove termination of the 3-rule system
{ [a, a] ->= [a, a] [a, b] [b, a] [a, a] ,
  [a, b] ->= [a, a] [a, b] [b, a] [a, b] ,
  [b, a] ->= [b, a] [a, b] [b, a] [a, a] }


The system is trivially terminating.
