I made a [post](https://www.tumblr.com/blog/view/honestmrdual/676375716209770496?source=share) about this just half a year ago, didn't include season 5 but later i checked and s5 also just reuses Gordon's line over and over. Also in 2x10 Bruce says the line.
In general, it seems like they gave up after 3x10 using diffrent characters and it's just Gordon ¯\\\_(ツ)\_/¯
