That's not how it goes. Shaking was proposed as an explanation for the triad, not observed as the cause. Then the syndrome was named after the proposed explanation and used as a justification to assume shaking whenever the triad was observed. The Guardian article makes this timeline clear.

Moreover, the Syndrome was used to justify suspicion of deliberate harm in cases where the triad was not observed at all, as I think in Roberson's case, if you read between the lines - no article about the case mentions the triad, only generic injuries that could, allegedly, only be caused by shaking.
