Snapshot general query

Scenario:

Create a snapshot (snapshot1) of managed disk (disk1) on vm1

Then create a managed disk (disk2) from snapshot1

Attach disk 2 to a new VM (VM2)

Are these statements then true?

If I delete disk1 after I create the snapshot but before I create disk2, it is no longer possible to create disk2 from snapshot1.

If I create disk2 from snapshot1 successfully, I can delete disk1 and snapshot1 without having any issues for disk2 and vm2.

Sound like an exam question - but it is actually related to what I want to do in my environment :)

Thanks!
