Hi Richard Carrigan - Thanks for reaching out over Q&A Forum.
Yes, there appears to be some discrepancy in the 2 links that you had shared from the training module. From the below link, it points that it shall ideally return an error.
Based on the usage mechanism, it should ideally not make a difference as underneath API will be called to make the operation.
I'll try reviewing it internally once again and shall confirm back on this one.
