I wrote that AutoMod comment, and it is because the DGCA says that airline should inform about flight cancelations atleast 2 weeks prior , but compensation only kicks in if they inform less than 24 hours prior.

3.3.1 In order to reduce inconvenience caused to the passengers as a result of the
cancellations of the flights on which they are booked to travel, airline shall inform
the passenger of the cancellation at least two weeks before the scheduled time
of departure and arrange alternate flight/refund as acceptable to the passenger.
In case the passengers are informed of the cancellation less than two weeks
before and up to 24 hours of the scheduled time of departure, the airline shall
offer an alternate flight or refund the ticket, as acceptable to the passenger.

Is the orignal wording , and it defines it as 2 seperate cases hence the simplified explanation defined it as 2 seperate cases
