You're right:

AMD Publication #33610, page34

"[Regarding erratum #131]
Systems implementing the workaround for erratum #169 should not apply
this workaround."

So it seems AMD recommends either or, but not both.

Page 59:
"[Regarding erratum #169]
The workaround for this erratum supersedes the workaround for erratum
#131. When implementing
this workaround, the workaround for erratum #131 should not be applied."

So we better implement only 169, and explain in the comments why 131 is
left out.
