It was our impression from viewing the video that this technique is very dependent on the dentist's skill in performing the needed steps (more so than with conventional construction, primarily due to time constraints needed to accomplish certain steps, and accomplish them the first time, properly, before the denture materials set). So in that regard, likely the dentist who fabricated your mother's denture is due as much credit as the system itself.
