Have you seen her? How do you know? she claims she has landed triples...
I have no idea what Kwan's intentions are, or what her current skill level is. Or Cohen's, for that matter.
This post is intended more generally.
However, a retired skater working to recover lost jumps or even to learn new ones is not an indication that the skater is necessarily planning a comeback to competition. Working on and sometimes landing various triples in practice may be a far cry from having enough current jumping skill to achieve results comparable to what the skater was capable of at the peak of his/her competitive career. There's a big difference between landing all the triples in isolation in practice and landing 7 or 8 triples, including combinations, in a 4- or 4.5-minute program also filled with difficult footwork and spins.
For example, in the mid-1990s, during the period when reinstatement was an option for skaters who had lost their eligibility and the overlapping period during which opportunities for pro skaters were at an all-time high, we saw quite a few professional skaters reintroduce jumps they had performed as amateurs to their repertoires that they hadn't performed publicly for a decade or more. Some even added new jumps.
Some skaters did return to competition briefly. We all know about the handful of reinstated stars (among the singles skaters Viktor Petrenko, having taken only one year off, was the most successful but couldn't manage another Olympic medal). Some other returning skaters had no delusions of glory but just wanted to get back into the swing of things competitively for their own satisfaction. But in other cases, the skaters may have had no interest in returning to eligible competition but wanted to regain the tough jumps for personal pride, and if possible to show off in shows or pro competitions where they could afford to leave out some of the medium-difficulty triples or to take lots of rest breaks with posing or two-foot skating in between the jumps.
For example, I once witnessed a 30-something coach who also had a non-superstar pro skating career taking an informal lesson from a more well known jump coach. The skater was attempting not only all the jumps s/he had performed as an amateur, but also a new, more difficult jump. But the successful triples were all performed in isolation, not in the context of a program and not, IIRC, in combination. The new jump was not performed successfully. And the pro programs I saw from this skater included only the easiest triples, also often unsuccessful.
So it would have been true to say that this skater was working on all the triples. But it would not have been true to say that this skater was at that time able to keep up jumpwise with even lower-ranked senior competitors at that time.
