Same, I always thought it was for organizational purposes, not the actually number of years it took place before chapter 1. My theory is Hitsugaya graduated the academy and joined the 10th about 25 years before the main storyline, and what has occurred the last two chapters took place about 22-23 years before the main storyline (I am adding with the time skip).
