[R] Identify does sort the locations

Using identify function, I think I should get the index of the selected 
points in the order I clicked them. This is what I read in the help. But 
I feel they are ordered. Please let me know what I missed.

In the following example, I clicked on the points labelled 7, 5 and 1, 
but I get 1, 5, 7 as output.

> set.seed(0); x = rnorm(10); y = rnorm(10); plot(x,y); text(x, y, 
> seq(x)); sel = identify(x,y); sel
[1] 1 5 7

Any help appreciated,
