They aren't really equivalent. Suppose you start with somevar equal to

1
2
3

and you say "delete line 2 of somevar". You then get

1
3

but if you say "put empty into line 2 of somevar" you would get

1

3

So they aren't really the same.

Check out the whole thing. Perhaps you don't actually have that line! 
Putting empty into a line you don't have creates the line, by the way.
