Yes, Buddha did meditate. This is for the pleasant abiding here and now.
From the discussion, What did Buddha do to pass his time? --
Some relevant info:
Then the Blessed One, having emerged from seclusion after the passing of three months, addressed the monks: “Monks, if wanderers of other sects ask you, ‘By means of what dwelling, friends, did Gotama the contemplative mostly dwell during the rains residence?’: You, thus asked, should answer them in this way: ‘It was by means of the concentration of mindfulness of breathing that the Blessed One mostly dwelled.’ …
This means that right mindfulness functions not only as a factor of the path, but also as a pleasant pastime for those who have fully developed the path and tasted its ultimate fruit.
