According to the `stock.move` fields definition:
`date` is the "scheduled date until move is done, then date of actual move processing"
`date_expected` is the "Scheduled date for the processing of this move"

The scheduled date of the product being produced in a
manufacturing order is the same scheduled date than written
on the manufacturing order.
