Thats probably because they need to verify the start date of the ticket - ie the first flight - so you are not going past the 1 year ticket validity from first flight. In which case, I'm surprised they didn't ask for evidence of date of first flight (eg BPs).
Note that OW does not revolve around you and they OW carriers generally don't know what each other are doing.
