In an interview with Swiss newspaper SonntagsBlick, Blatter denied allegations the 2018 and 2022 World Cups had been bought by Qatar and Russia, respectively, and instead turned his attentions to the 2006 tournament.
"I remember the award of the World Cup for 2006 when, at the last minute, someone left the room and so, instead of the voting being split 10-10, it was 10-9 in favour of Germany," Blatter said, incorrectly recalling the voting tally.
"I'm glad I didn't have to make a casting vote but, well, that person suddenly got up and left. Maybe I was too good natured and naive."
When asked outright if he was suggesting the 2006 World Cup had been bought, Blatter said no but it was "just something that I noticed".
German football secretary-general Helmut Sandrock defended his organisation and, by extension, Dempsey, fixing the spotlight on Fifa itself.
Dempsey always insisted there was nothing nefarious in his abstention, citing "personal reasons" and "intolerable pressure" in his decision to cast no vote.
