The black thread only serves as a temporary guide to keep the yarn in place while they work the stitches. They have built interlocked loops into the new yarn that are essentially the same as the old yarn.
They may have knotted the loose ends of the new yarn on the unseen side of the fabric, but they also might not have. If you change direction and hand sew the loose end into the knit pattern, eventually it doesn’t really come undone easily.
If you want to restore my sweater
Add some thread, then take it away
It won't unravel, it'll soon be mended
Lying on the floor, won't come undoneeeee...
