The difference between string::rfind() and string::find_last_of() is:
str.rfind("abc") finds the complete substring "abc" in reverse order
str.find_last_of("abc") finds any character of a/b/c from the end of str.
Is my understanding correct?

Well that would certainly be confusing...
You could always try it and find out, but that's not the way I read it here:
http://www.cppreference.com/cppstring/rfind.html
If str is "abcabc", then rfind("abc") will return 3 and find_last_of("abc") will return 5. The difference between the two that I think you understand correctly is that find_last_of searches for any one of the characters provided, whereas rfind searches for the entire string provided.
