This is uncanny, I was going to write almost this exact comment. I've been told mine is due to a deficiency in working memory, which can then lead to the brain not converting to long term memory. something that ADHDers present commonly with.
I'm in the opposite camp - I also have poor working memory, but instead I have extremely good episodic memory. Good enough I have to remind other people about our shared experiences routinely. I never claim to have eidetic memory but I've only met a couple other people who have memory like mine (one is my mother, so that's kind of cheating)
It's interesting though because I associate with a lot of what the article is talking about with spatial and knowledge memory too. I often have to remember where something was to "step into" the memory again.
