Nodes numbering in METIS 4


I'm using Metis 4 for FE unstructured mesh partitioning. My elements are either hexahedra (3D) or quadraliterals (2D). According to the Metis 4 manual, the nodes of such elements have to be numbered clockwise. But is it really important? My understanding is that the numbering is used to build a graph, so anti-clockwise also should work as soon as it's consistent, is not it?
