MBS chapter on Fixed income (asset/liability) terminology liability, investor, question, balance, savings

Colum

Reading 45 - question 21 asks : which MBS should an investor of a savings and loans choose ( longer maturrity vs shorter maturity) that is a better off from an “Asset/Liability” perspective.
What do they mean by ” Asset/liability” perspective???  I know it’s like saying from a balance sheet perspective… is that all?
