Whoever wrote that article is confused, since in the table in the section labeled “Analogy vs Simile: The Differences” they have several entries the wrong way around (compared to the two paragraphs preceding it).
It seems to me that you could use the same comparison for either an analogy or a simile. An analogy would usually be in the present tense, “X is like Y”, and followed by more explanation of the concept the analogy is meant to illustrate. A simile would more frequently be in the past tense as part of a narrative, and more frequently use other verbs than “is”—”X moved like a Y”—and probably wouldn’t extend beyond the current sentence, usually not even beyond that phrase. I think a bare statement of “X is like Y” might go either way.
