Yoga term: none
Even though I say none for Yoga term, it is a slight variation of a pose called Hero; Virasana. Which has the feet to the sides of the hips. This is actually a Japanese posture called Seiza. In Japan there are no chairs or were no chairs and people sat like this. This is also a meditation posture. Here it is being presented as a resting pose and a stretch for the front of the ankles.
Alignment points:
Sitting with knees folded under the body. Knees can be together to two fists apart. Whatever you find most comfortable. The feet are with the toes facing behind you with the big toes touching. The upper body is the same as of yo were in a seated or standing meditation position.
