Yes Maxim, I had understood your point. My test actually ran for 60 to 65 seconds which means it took 5 additional seconds to process the requests. Even access logs says the same. Also, on more powerful machine, I get expected result for the same test i.e 500 req/sec load but start seeing difference at relatively higher load.It seems to me that a results also depends on the resources available on the machine running Nginx. Surprisingly, CPU was not hitting the peak on both the machines.I am using CentOS systems for this testings.

Actually in another test with plain HTTP requests, I observed the same issue of more requests than expected getting processed. However, for HTTP case, this behaviour appeared at 700 req/sec input load instead of 500 req/sec as in HTTPS. In this test requests got processed within 60 secs.

With all the test results, I am being forced to think that Nginx rate limiting may not be able to stop DDoS attack with very high input load but is decent enough to handle sudden spikes and load which is slightly higher than configured rate limit, and computing power available also plays some role here. Do you think I am right?
