Forum:Cybernetic Hidden Technology

So my friend had a CyberDark Horn and a Cyber Barrier Dragon on his field, and two facedowns.

I had a Diamond Dude, Doom Lord, and Dreadmaster.

I attacked with Diamond Dude on Cyber Barrier Dragon to get rid of it's effect.

Now, Dreadmaster Attacked.

MY opponent flipped Cybernetic Hidden Technology face-up, and to that he chained Call of the Haunted, bringing back his Cyber valley, and then, he said it meant a replay, so I attacked again, and he chained Cybernetic Hidden Technology.

My question is, if I attack with the same monster during a replay, does it count as another attack? Since then he can't chain Cybernetic.
