In-form City had struggled to get the better of the Magpies in the first period, but Danny Haynes was sent off just a few minutes before the break for a high tackle on Jordan Clarke and it changed the complexion of the game.
Just two minutes into the second half, Blair Adams crossed for Leon Clarke and he smashed the ball home via the underside of the crossbar and then doubled his tally after a mistake from Mark Fotheringham.
That put Clarke on 11 for the season - one ahead of his young striker partner Callum Wilson.
But Wilson then charged through on goal, rounded Bartosz Bialkowski and slotted into the net to equal things up with Clarke.
City manager Pressley said: "When you come in at half-time and they have just had a man sent off, they can come out with more intensity so we had to get the message to our players to work even harder.
"We upped our work-rate in the second half and it was magnificent. The players are doing exceptionally well right now.
"There is no doubt there is a wee bit of a competition going on there between Callum and Leon, but I like that as it brings an edge to their performance.
"They are working so hard for the team and they are getting their rewards for that.
"Leon's two finishes were of a man brimming with confidence and I was pleased with the two of them - but I was pleased with the whole team.
"It was another clean sheet too and we haven't lost a lot of goals of late."
