Default blockMesh walls numbering sequence

Hi Folks!

I'm new to OpenFoam and I built the blockMeshDict for the cavityClipped example. The Courant number is exploding and the only difference between my blockMeshDict and the example's is that I have, for instance, a fixed wall defined as (1 3 11 9) and the example has the same wall defined as (3 11 9 1).

Hence, my question is why is this happening? The sequence is the same and the arc goes the same way.

Any help would be greatly appreciated.
