The difference is "a-bank" was changed to "bank". I was doing this out of curiosity to see if there would be a drop in comment spam, and also to see if all references to the post would be updated. It looked like references were updated. But that may be because it was made into a redirect and the references are not really updated, but end up at the post due to the redirect.
I'm just curious what's going on here. BTW, 96% of my comment spam goes to this one post. I did once turn comments off for it, and that stopped the spam. I turned comments back on a week later and the spam resumed. Obviously that specific URL is being distributed among comment spammers. I'm trying to play around with them some to see how they operate.
