It's all nonsense, of course.
Yoga is yoga is ONLY yoga. The only problem with that obvious statement is that it, too, is all nonsense. Yoga is made up of eight limbs, so to do say one "does yoga" is completely devoid of meaning. One might say that she practiced pranayama or asana or observed the yamas and the niyamas, but those phrases are aggregations as well. To say one "did" any of them is completely empty. The only thing you can practice is an individual thing, not a category. You can't even do downward dog. You can do THIS downward dog. The one you do in the moment. The one in the now. Your next downward dog will be something completely different that is united with the previous downward dog mostly by linguistic convention, not reality.
Yoga bleaching is real, and the worst form of yoga bleaching might be when one tries to substitute something else for an element of yoga. The practice of individual asanas confer a set of benefits that, by definition, can come only from the practice of asana. Meditation, and nothing else, confers the benefits of meditation. A thing is a thing, and nothing else is that thing.
Feel for the yogalebrity. She knows she is not practicing asana as she once did, and she misses it. Her attachments have gotten her all twisted up, and the tragedy is that she need not be. She has made her choice, and her choice is just fine. Other things are worth doing! Other things, like teaching and traveling and making enough money to not live in a van down by the river, offer their own rewards. If a mature adult weighs the rewards associated with an activity that necessitates she lessen her asana practice and finds that they outweight the costs, we should celebrate such enlightened decision making. Many paths to the top of the mountain and all, but lying to one's self about what one is and is not doing is a sure way to steer directly into oncoming traffic.
