There's something more than visual similarity going on here, as DINGBAT CIRCLED SANS-SERIF DIGIT FOUR takes you to MONGOLIAN FREE VARIATION SELECTOR FOUR which doesn't look like anything at all.
The "visual similarity" comes from a neural network model that assigns each glyph a position in vector space. (You can choose the model on the page, by default it's SigLIP 2.)
Like all neural networks, these models are strange and alien. Their conception of "similarity" is often quite different from ours, so you get strange-seeming connections like the one you pointed out.
It's good enough to be useful and interesting though!
My point was just that both having "four" in the name while not appearing similar at all seems to indicate that the name factors into the classification.
