Yes... but if you are packing these in styrofoam then you will still be OK, unless you are packing a case full of these oversized bottles it will work, as styrofoam has enough flexibility to make room for larger bottles but still keep the outer cardboard box in the same shape. As long as the styro carriers fit in the duffle bag the above poster will be OK.
