I think the show has such a fast pace when compared to the books that, to keep Sookie and Eric apart because of some short term memory loss, just wouldn't work for the show. In my opinion, the story demands for them to dive into the consequences of what they've been through, both romantically as well as individuals.
While I agree with previous posters that Eric's retaining his memories of being with Sookie is necessary for the expediated timeline of the show, what bothered me about the way it happened was how calm he seemed to be as he reconciled these memories with his other memories. This was a character that, despite clearly having feelings for Sookie, rarely allowed himself to reveal them to her except in ways that emphasized his (both perceived and actual) control over her. That he could suddenly remember that he not only offered, but deeply desired, to give up his identity and this control without feeling slightly humiliated and angry and confused seems completely OOC for me. Witnessing Eric attempt to form the hybrid between "him", as he referred to Amnesia!Eric, and "me" would have been, to me, a much more plausible and interesting roadblock for he and Sookie to face than her continued feelings for Bill.
ETA: I realized I should probably make it more explicit why I am posting this in the book thread (I'm still quite new here!). In the books, we obviously saw Eric dealing with the very mixed feelings he had when he finally learned what he had offered to leave behind for Sookie, and those moments were some of my favourite in the series.
