Cavalry Breakthrough with Combined Attack

Just noticed a small but IMPORTANT addition/clarification in the 2nd Edition rulebook, page 15, right column top.

A Combined Arms Combat may be declared with a Bonus Attack.

So now it´s possible, to save the battle dice of any ART, to support a CAV in a breakthrough bonus attack!

Hi,
Does it mean that a same ART can support twice the same CAV during its first attack and then during its breakthrough ?
(Sorry for this question, but I'm not very aware of english language and don't want to make misunterpretations of the rule)

NO, each ordered ART may only battle once,
but you can choose or spread up (if you ordered more than one ART), which battle the ART supports.

OK
In fact, we've been playing that way since the beginning (An ART can fire only one time during a turn)...
Combined attack is very powerful and when it is well prepared can make your opponent suffer severe losses to his units.
