You need both The Dark Below and House of Wolves to qualify for Destiny: The Taken King – Digital Edition

In order to download Destiny: The Taken King – Digital Edition, you must own Destiny, The Dark Below, and House of Wolves. These licenses must be owned under one account. You will not qualify for this offer if the content is split between multiple accounts on a single console.

"poti avea ultimul "dlc" fara a le detine pe primele doua" - Nu, nu poti. Cu alte cuvinte, nu poti achizitiona sau activa TTK pe un cont care nu are licente valide pentru ambele expansion-uri (deci ceea ce stiai tu nu e corect).
