Yoga is a way broader philosophy and discipline in Hinduism than in Buddhism and Jainism. In Hinduism, Yoga means more than just asanas and pranayam. For instance, the Bhagavad Gita define 4 types of yoga - Karma, Jnana, Raja, Bhakti - only one of which (Raja) includes asanas and pranayam. Also, though there is no consensus on this, yoga may have existed even before the Vedas. In either case, the philosophy is definitely there in Vedas and Upanishads (Hindu scriptures), which pre-date Gautama Buddha or Mahavira Jain. It makes complete sense to show the Hinduism info-box on top. Another suggestion is remove the info-boxes altogether. After all, the article also goes on to discuss about influence of yoga on other religions like Islam and Christianity. But showing the info-boxes in an alphabetical order does not make sense.
