Correct.
G22:

Robots may only actively control three Basketballs at any time.
Violation: Foul per extra Basketball


Moving or positioning a Basketball to gain advantage is considered actively controlling. Examples are “carrying” (holding Basketballs in the Robot), “herding” (intentionally pushing or impelling Basketballs to a desired location or direction) and “trapping” (pressing one or more Basketballs against a Court element in an attempt to shield them).

Also correct—no further support needed here.
