The intention here was never to have deposit insurance at a higher level in perpetuity. What this is clarifying is with regard to when two institutions amalgamate. Let's say, for example, you have $100,000 in institution A and you have $100,000 in institution B. You would have $200,000 of deposit insurance coverage once those two institutions amalgamated into institution C.
This is to clarify that it is not forever. It's not in perpetuity. It's only for up to two years following the amalgamation of those two institutions.
