This is the Mass and altar set-up outside the Basilica of St. John Lateran for 2014's Corpus Christi Mass. The altar is clearly ad orientem with the central crucifix and faces in the traditional manner as at all of the Major Basilicas in Rome except for one and that is the Basilica of Saint Paul outside the Walls which traditionally even prior to Vatican II celebrated Mass toward the west, toward St. Peter's Basilica.
Here Pope Francis is clearing celebrating Benediction of the Most Blessed Sacrament at the conclusion of the Corpus Christi Procession 2014. There is no doubt to where His Holiness prayers and adoration are directed in this position of the celebrant before our Lord!
Pope Francis has continued Pope Benedict's altar arrangement everywhere he goes albeit with more modest and proportional accoutrements. And yes since the Solemnity of the Chair of Saint Peter, the four to six candles are angled more and the episcopal candle is now to the side (which is traditional also).
But make no mistake, Pope Francis has kept the celebration of Mass and Benediction of the Most Blessed Sacrament ad orientem or toward the Lord!
