Checking in at a hotel is different from booking and checking in. Whose interpretation is it?

It should be deducted at the time of check-in, because the deduction is caused by the actual check-in, not the hotel loss caused by the reservation or the corresponding deduction, so it should be deducted at the time of check-in, and it is likely that the reservation person helped book the hotel at the time of check-in, so it should be deducted at the time of check-in.
