So I imagine this flashback arc will show us two things;

1) The mysterious person who was in Jugo chambers way back. Because it seemed relevent then, and I imagine it will return to relevance now.

2) What happened in the original invasion of the Soul Society. Hopefully with a sense of some brevity.
