Because partitioning & formating are two separate processes involving at a minimum of two separate programs: the partitioner & the formater.

Imagine a mini-van or a SUV without any bucket, captain, or bench seats installed. That is similar to an unpartitioned hard drive.
Then add a captain's driver seat and label it for Bill The Driver. This is similar to making a single partition on the hard drive.
Then add a 2nd row bench seat for and label it for Linus. This is yet another partition.
Then make Bill sit in his seat. This is similar to formatting.
