Unexpected exception in JKA

[syainkn]

 

I've known that when I'm about to use the dark side force skill, the light side force skill which I'm using is suddenly disabled.

But look at this picture !   I'm using Force Drain while I maintain Force Protection and Force Absorb(Tutaminis).  How is it possible?

So...  Now... Do I gain the balance of the Force?  It is possible only when I use Force Drain closely in front of the opponent.
