for loop question

In the windows version of R (1.3.0) is the following a bug, a
known problem, or expected behavior:

 > for (i in 1:2) {

 + for (j in i+1:3) {
 + print(j)
 + }
 + }
 [1] 2
 [1] 3
 [1] 4      ????
 [1] 3
 [1] 4      ????
 [1] 5      ????

 >

It's expected behaviour (if you expect it)

Try
  i<-1
  i+1:3
  (i+1):3

to see what is going on
