If the MX is actually being built that slowly, the most likely reason would be a parts shortage from a vendor. If they rejected a parts shipment, it might set them back a few weeks to a month. Instead of running out of the part and stopping production, they might have rationed. Rationing would prevent the possible headline "Tesla Halts Model X Production".
Since real retail customers posses actual Model Xs, I doubt there is a fundamental problem here.
Although I expect Musk has considerably more respect for the difficulties of actual auto manufacturing today than he had five years ago.
Another possibility is that they have accumulated several improvements in design, parts and manufacturing and they are now testing those out at a low production rate. The wait time can be both from internally sourced components as well as from external.
