Okay, but I thought the point of this mandate is that he wouldn’t any longer do that?
Above is a video of the Mass, offered in Latin, last Sunday May 22, 2022.
I don't expect that you will or should watch the whole thing, but if you fast forward through it you'll see the Priest mostly facing the Altar/Tabernacle/Crucifix, and sometimes facing the congregation.
Most of the Mass consists of "Prayer", that is the Priest (and congregation) speaking worship, praise, thanksgiving, and honor to God. At those times, the Priest faces the Altar etc. When he is reading the Scriptures, preaching, or blessing the congregation, he faces them.
The topic of this thread is a mandate to do what the priest in that video is doing.
