Actually, that is rare (so stop pretending it's a well know comic fact when it isn't). Things of this nature can and should be taken as the dialogue actually first occurring before the action and finishing during the action.
Sometimes comics accidentally go against common sense. If that is the case (not necessarily the scan you showed does this) then those instances can't be used to prove a Pro about a feat.
Anyone knows that there is two types of magic casting.
1. magic due to chanting first
2. magic without chanting.
Clearly, in comics characters wait for the other to finish chanting before making an action. This is for the sake of the story and not because the chanter is actually chanting at instant speed.
