PARALLEL_MIN_TIME_THRESHOLD Contradictions

PARALLEL_MIN_TIME_THRESHOLD initialization parameter controls which statements are candidate for parallelism. 

As per MOS, this parameter is set to 10 seconds while Oracle documentation claims that it is set to 30 seconds. Now who's correct ??? Seems like it's a documentation bug.

Below are the links to both Oracle documentation and MOS article:
