Basically this is saying that for the full multiplayer experience, you will need to buy both of the expansions.

I think people will buy them, even if they complain and say they won't even buy SC2 right now.

Another very interesting thing is that you will not beat/cleanse Kerrigan in the Raynor missions since she is the focus of the second campaign.

Also it is possible that protoss do not win at all, just that they are able to restore status quo after kerrigan pwnage in campaign 2. That is at least how the warcraft campaigns ends, the nelf campaign ends with you thwarting the demons tries to destroy the world of azeroth, and the end of TFT ends with you barely rescuing the lich king from getting destroyed.

At least this are my estimates that the campaigns are about:
Raynor: He takes control over most of the human settlements.
Zerg: They almost conquers the whole sector and pwns all resistance.
Protoss: Is about surviving the zerg, after a few missions Duran realizes his plan and unleashes the new cross breed driving the zerg back. In the middle of this you as the protoss learns of the ultimate weapon which would restore balance and it all ends in a climax timer based defense mission a la world tree of wc3 with zerg/cross breeds attacking from one side each and you get help from all of the allies you gathered up from the diplomatic campaign.
