Lifts are not allowed in latin or ballroom - they are only ever allowed in showdance.
There's a definition that a lift is any move that occurs when both feet are off the ground in a move that the lady couldn't do unsupported. But there are grey areas within that definition and it doesn't really hold completely true.
Both legs should never be off the floor for an extended period of time - that will ALWAYS be classed as a lift. However, if there's a brief move where the above applies, but the man's arms don't actually go up but instead may go down or forward, it's hard to call it a lift and common sense tends to come in with these moves. Karen called the move Artem and Kara did a dip, because Artem's arms and Kara's body actually went downwards - even if her legs swung out and both were very briefly off the floor. (I assume, she may have kept one on the floor - i'd have to watch it back) Dips aren't considered lifts and they are such a common move in Latin, you can't really knock Artem for including it.
One of the reasons there are no lifts in dancesport is that it is dangerous when there are so many couples dancing on the floor at the same time. Dips are often done in the Paso (although has moved into other dances like Cha Cha), as the music has three highlights and it makes a good highlight to swing the lady around and finish in a dramatic line held up by her partner. The World Champs for example have a trademark Paso entrance which shows the same kind of thing and it's all definitely allowed:

Again, the man's hands/arms don't go up and the lady's feet aren't both in the air for very long - one is quickly replaced by the other. It's more of a step over with a ronde, which is supported by the man and driven by momentum rather than lifting. It's all very compact and controlled as well and the weight stays low down.
However if you did this type of move in a comp and you weren't controlled and the lady's legs were swinging quite high up, it still may not be called a unequivocal lift, but a judge would come and give you a warning and would say that it must be taken out of the routine in the next round. On the premise that it's dangerous for other couples. That's why you never see jumps in comps, where the lady swings round and scissor kicks her legs out behind her. May not be a true lift, but it would be dangerous. There was quite a storm in Blackpool last year as the World Champs were given a warning and told to remove a backwards kick in their Rumba. It could be dangerous to other couples.

Sorry - I've waffled on! I hope my explanation makes sense. I'm not an expert, but I follow dancesport and go to comps regularly and the above has always been my understanding of the lift stuff.
(Can't really remember what Aliona and Matt did, I'd have to rewatch it).
