I got the 1 free night for every 2 stays offer..
Now, I went thru the T&C's of the same and I believe that MR points will be awarded for the qualifying stays ?? Is this understanding correct ??

Maybe I am wrong, but I guess this offer is a decent one compared to the stay XXX get yyy points, since this gives 2 nights in a cat 1-4 hotel making the points value anything from 20-40k for the redemption.. and much better than stay 20 get 25/39k MR points IMO..
