Thanks so much, I knew there was some kind of term of concept for that but couldn't find it!

I remember back in the early web days I was trying to make a post on a forum with something about Dick Van Dyke, getting a double-whammy name block. He already unfamiliar to the younger people even back then, so none of my attempts to explain who I was talking about worked. I couldn't even say what show he starred in for them to look up, since it was also called The Dick van Dyke Show.

No idea and not sure if it's right. They could be attempting to match something across whitespace or line breaks and gotten greedy. Or maybe it is just a string match and not regex and they pasted the wrong string, but that still feels weird.
