I think in the auto_ptj_mjj documentation refers to directly-produced jets (e.g. the forward jets in WBF) and not decay products. I would expect any cuts on the latter to be solely controlled by the cut_decays flag. In this case, I would agree with Rikkert that this is a bug. Moreover MG/ME gives (me at least) a wildly incorrect cross section for the process. This is exactly the problem I was describing in my bug report #1311186.
Dear Olivier,
