Does it meet the criteria

[Siri]

There is nothing in the definition of herding prescribing that the bumping robot be responsible for its own actions. The closest G12 to this is trapping, as there's technically an "attempt" to do something (though the Q&A has chosen to ignore this, and the parsing makes it unclear if trapping occurs during the attempt or if it itself is the attempt).

Due to the lack of a no-call rule this year, the bumper color of the causer doesn't technically matter either. Red pushes blue to repeatedly bump a blue or red ball, blue pushes blue to do so, it's all grammatically the same call (the result being either a foul, barring G14, or an assist-eligible possession).

You feel correctly. Standardization requests have as yet yielded no results.
