Because it is approved in an HR system and planning happens in a delivery tool. The manager approves a fortnight in July and the project plan still shows that person at full capacity for those weeks.
The collision is found when the milestone is missed, and everyone involved had the information in front of them at some point.
A leave request goes to the reporting line in Nest and, on approval, reduces that person's available hours in Loop for those dates.
