Although much has been made of the incident, Steve, like his manager, reckons it is a clear indication of commitment.
"It was a general discussion about the goal, and just a case of heated professionals working it out - that's what you get because the lads are passionate about winning," he says.
Indeed, Steve is far more concerned about the performance overall from the 11 players who got the draw with the second division side and admits: "It was not a classic and we gave a bad goal away again - which gave them a lift when we were pretty much in control.
"I am obviously delighted we won but it should have been buried before extra time and that is the disappointing aspect, though they really did get bodies in front of shots."
Carl Muggleton, the opposition keeper, had an uncanny knack of guessing who would shoot where on Tuesday, and there was a anxious moment when Steve's spot kick crept under him.
"He got a bit close to mine - and I am just delighted it went in," he admits.
Steve now hopes that his team mates can serve up a treat at home on Saturday - and particularly reward the fans who made the trip midweek despite the game being live on Sky TV.
"All credit to them - it was big support with maybe 700 or 800 there, and they had to go to work next day so it was appreciated," he says.
"Life will be even better if we can beat Birmingham on Saturday."
