Correct- just has to be in an SKF- EITHER of these:
2-14-2
a. A player is in position with a knee on the ground 7 yards or more
behind the line of scrimmage, in position to be the holder and
receive the long snap and with another player 3 yards or less behind
that player in position to attempt a place kick, or
b. A player is 10 yards or more behind the line of scrimmage and in

EXCEPTIONS:
1. On first, second or third down, when A sets or shifts into a scrimmagekick formation as in 2-14-2a, the snapper may be a player numbered 1 to
49 or 80 to 99. If Team A has the snapper in the game under thisexception, Team A shall have four players wearing numbers 50-79 on its
line of scrimmage. The snapper in the game under this exception must be
between the ends and is an ineligible forward-pass receiver during that
down unless the pass is touched by B (7-5-6b).
2. On fourth down or during a kick try, when A sets or shifts into a
scrimmage-kick formation, any A player numbered 1 to 49 or 80 to 99
may take the position of any A player numbered 50 to 79. A player in the
game under this exception must assume an initial position on his line of
scrimmage between the ends and he remains an ineligible forward-pass
receiver during that down unless the pass is touched by B (7-5-6b)
