The purpose is to be able to use domains you (your organization) owns for things like email, chats/meetings, etc. It's not mandatory, as you get a default domain with O365, but it's something that pretty much every business out there does. Back in the day you were even able to host a webpage with your custom domain name in O365.

Hi johnjohn-0472,

Agree with michev. Normally {tenantName}.onmicrosoft.com is the default domain of Office 365. You could create accounts specific to one domain by adding your own domain.
