OK, I just found what Carrie Ann was apparently calling a lift. Someone pointed it out on YouTube, that when the guys pull the girl over their leg, it's considered a lift in the Tango but not in the Argentine Tango.
It's at :43 to :44 in this video: YouTube - Dancing With The Stars - Team Tango
I thought it looked great, and Kelly thought it WAS the Argentine Tango. That's what she called it in the interview.
