Is it normal for a guy friend to reference an old outfit like this?

Im probably overthinking it, but still, i want to ask.
I send this guy videos of my outings and outfits
I've texted him a couple of other things he could have responded to, but I haven't heard from him in 2 days, so of course, I thought he was busy. This morning, I got a text and a pic of a tie that he found in his closet. He told me that it matched my outfit. Now, the outfit he was referring to was something I sent him a month ago, and i sent plenty of other stuff since then. Was it a random memory that just popped up when he saw the tie, or was he watching my video recently?
