In my opinion, it is not correct. If anything, (assuming a R-H 1/4 Tag), I would expect a Cross Extend and Hinge because the centers pass right shoulders with each other, and therefore must pass left shoulders with the outsides.

If you look at our Ceder Chest Definitions, we only define Weave from a Mini-Wave Box, applicable T-Bone Box, or a Single Eight Chain Thru.

From my recollection, the CALLERLAB and Big Five defintions also allow a Single Trade By (expecting the Ends to 1/4 Right as the Centers Left Touch 1/4) which I consider to be illegal.
