Glory to Jesus Christ!

I was watching the Vigil from December 12 from the Church of the Nativity. When I got to the Kathismata during Utrenja/Orthros, I was (pleasantly) surprised to hear that instead of the entire psalter reading, there were antiphons with select verses from each Stasis/Slava with a refrain of Alleluia, just like "Blessed is the Man/Blazhen muzh". Is this the normal or customary way to sing the Kathismata?
