I'm beginning to think you must be one of the easyJet customer relations or commercial people.
That interpretation is not sustainable. It says that you are entitled to re-routing at the earliest reasonable opportunity. A reasonable opportunity is a flight with another airline and the CAA as the National Enforcement Body for EU261 takes that view. In the guidance covering cancelled flights, the CAA state:
2. Choose an alternative flight
If you still want to travel, your airline must find you an alternative flight. It’s up to you whether to fly as soon as possible after the cancelled flight, or at a later date that suits you.
Although most airlines will book you onto another of their flights to the same destination, if an alternative airline is flying there significantly sooner or other suitable modes of transport are available then you may have the right to be booked onto that alternative transport instead. You can discuss this with your airline.
easyJet, just like any other airline, has an obligation to re-route you which may extend to re-booking you on another airline if that enables you to reach your destination on the day of travel that you have booked.
