Restricted to the Dugout or Ejection

[Just Curious]

Questions #12 & #13 in the Federation Study Guide deal with player's failure to wear batting helmets and catcher's protective equipment respectively.
My question is concerning the difference between the penalties.... Restricted to the Dugout (RTTD) and Ejection.
RTTD is self explanatory. On the other hand, Ejection is the puzzler. The rule's book states in 3.3.2 that players restricted or ejected shall remain in the dugout/bench area, whiles coaches that are ejected shall leave the vicinity of the playing area. So what's the difference? And what happens if one of these restricted or ejected players decide to cause further problems from the dugout?
