Not really. Forward guidance aims to direct market thinking on short term interest rates up to a max of about 18 months. I dont think any bonds influenced by that could be termed "longer dated". The examiner was wanting students to have read about the US "operation twist" that was ongoing at the time of the exam. It involves selling short and buying long dated bonds to twist the yield curve. So long as the amounts are the same, the balance sheet is not expanded.
