I am not familiar, so that may be the case. However, I think the bullet use goes beyond what that linked document describes.

Sometimes the bullets include:

• A statements and a question. Why?

• Only a dependent sentence clause,

• Like this

• Which is odd.

• Sometimes complete sentences are punctuated.

• Sometimes complete sentences are not punctuated

Sometimes the lists used bullets instead of commas, hyphens, and semicolons.

Sometimes the same lists also contained explicit commas, hyphens, and semicolons within points.

The effect, at least for me, was a feeling that the format had little underlying rhyme or reason. Kind of like an ad-hoc ramble

That's pretty much my impression any time I read an Axios article. They took a normally formatted article with paragraphs, and separated out random sentences and phrases into bullet points. They try to introduce some cognitive organization around the concepts of "what happened" and "why it matters", which isn't terrible, but often it just seems like bullet points inserted at random.
