Yes, it is.

I generally find it quite useful to see the C function a change is 
happening in. That's what the @@ line is for.

By the way, the $NetBSD could also appear at other places. See 
misc/openoffice/patches/patch-ak, lines 9--10, for an even worse 
example. These lines are excluded from the checksum and could be forged 
without changing the checksum.
