So does that mean, a XMPP client implementation MUST add a presence

It's more magical than that.
If I send you a <presence type='subscribe'>, the server adds you to
my roster instantly.
If you respond with a <presence type='subscribed'/>, your server adds
me to your roster, and my server updates your entry in my roster.
At no point do either of us need to directly manip[ulate our rosters
- we'll simply be told about the changes.
In practise, many clients add an entry to the roster prior to asking
for a subscription in order to set the name and group, but it's not
needed.

I think you've misunderstood what the roster is - it's not a simple
addressbook, the roster is the authority for who is subscribed to
your presence, and who you're subscribed to.
So removing someone from the roster actually removes their
subscription, and accepting a subscription will place them into the
roster if needs be.
