Please explain this TSO rule

[Vince148]

7.1 Position of the Players at the Snap
7.1.1 The offensive team must have the following in their formation:
(a) No more and no less than seven players on its line of scrimmage at the snap.
(b) All players who are not on the line, other than the snap receiver under
center, must be no farther than 5 yards from the line of scrimmage at the snap.
(c) All guards, tackles and tight ends must be at least 1/2 yard behind the center.
(d) Offensive linemen may be elbow to elbow for minimum distance.

This rule makes it appear that RBs have to basically be lined up or stacked right behind the OL. Is this true? Could you not run a spread formation with the RB(s) 10-15 yards behind the LOS?
