I agree that at some time it will step to line 7 after executing line 6 and at other times it will step to line 6 after executing line7 as they both at the same iteration. However, my concern is that for the "first iteration or first time" line 6 should be hit ahead of line 7 no matter on whether we using step or using stepi. That's to say, the first hit of Line 6 or Line 7 should be consistent between step and stepi.
