On review of study material, I understand
1. As per the Great exposition school, all accumulation of merit happens on the path of accumulation. Therefore, A bodhisattva has not abandoned afflictive obscurations.
2. Also, bodhisattva progresses from heat stage of path of preparation to being a Buddha in one single session as per this school.
As per the two points above, my question is not valid in context of Great Exposition school.
