Can someone smarter than me explain if this system maintains anonymity?

To a layperson, statements like the one below raise a flag. If I can track it electronically, is it also possible for someone else to see who voted for whom?

"After the election is complete, the tracker codes can be used by voters to confirm that their votes were not altered or tampered with and that they were properly counted"

Again, to a layperson the above statement seems potentially at odds with the one below at first blush (because I don't understand the technology):

"With homomorphic encryption, individually encrypted votes can be combined to form an encrypted tabulation of all votes which can then be decrypted to produce an election tally that protects voter privacy."

So we have privacy but electronic traceability to the individual voter? To the uninitiated like myself, it seems like we'd have to choose between electronic traceability and anonymity.
