TI-API: Backlog API (backlog/orders) separate orders

Tool/software:

1) Is it possible that when placing an order via backlog API ([POST] backlog/orders) for a product with a quantity (for example) of 10, it gets split into two separate orders with different order numbers (for example with different scheduledQuantity and requestedQuantity)?

2) I’ve noticed that in the case of the backlog, sometimes when I submit an order ([POST] backlog/orders) containing several different products, the response splits it into multiple separate orders with different order numbers. Could you explain in which cases the order is split like this? With the Store API, a single order is always returned.
