It's cut on a cnc router table, which does not handle regular wood very well. The dimensional stability and anisotropic nature of plywood is a better fit for most automated cutting methods. If you try to CNC route most regular dimensional lumber it has pretty bad tearout and splitting unless you use a really fine cutter and go slowly (which takes forever).
