498 // The new flow cross handles consuming excessive offers differently

502 // offerbook and per quality. This test shows how they can differ. Set

504 // below the limit. However, if all the offers are consumed it would

511 // offers. With the `FlowSortStrands` feature enabled, if the total
512 // number of offers consumed by all the steps combined exceeds 1500, the
513 // payment stops. Since the first set of offers consumes 998 offers, the
514 // second set will consume 998, which is not over the limit and the
515 // payment stops. So 2*998, or 1996 is the expected value when
