This means that it does not apply to auxiliary/supplementary attacks that also generate BC; such as "50% to drop 1-2 bc on x" or "x% chance to produce additional bc on x". All of the effects that generate BCs are not affected by the sphere. Only BC you generate specifically with your BB/SBB/UBB or normal hits are what this sphere improves the drop rate for. I hope this helps.
