One more point. What would happen if 2 records are added close together? The first has ID 3 and the second has ID 4. Autonumber now sits at 4. The first is reverted and the second one is saved. If you had what you wanted, the autonumber would be reverted to 3, but the second record now has the number after the current autonumber count. The next record addition now creates a duplicate number.

One thing to note is this is NOT a pure PK generator. It is only an autonumbering feature. The autonumber seed value can be reset at anytime so duplicate values can be generated. The only way to enforce PK values is still through creating a PK index.
