Non dimmable LED's tricked to dim?

[Paddy]

Has anyone seen the trick where you have several LED's on one switch to make non dimmable LED's dimamble. see link;

How to make an inexpensive non dimmable LED light dimmable - YouTube

Basically they use one dimmable LED and the non dimmables all begin to dim. The reason I ask; I have a large room with 4 switches operating 32 40 watt lights. I can get those low cost 60 watt equivalent/9 actual watts but they are non dimmable.

Also, if this does work, why?
