Is this a better way of installing tubing for radiant floor heating?

This is a build residential build in Germany. I found it interesting because as you can see the tubing was added after the walls, framing, etc had been built whereas in the on this site I typically see PEX being incorporated into the slab itself.

    Here in the U.S., there are lots of radiant floors installed the same way that is shown in the photo from Germany. Embedding PEX tubing in a concrete slab is only one way.

    PEX tubing can be stabled up under an OSB or plywood subfloor (with or without aluminum transfer plates), or it can be installed on top of a subfloor as shown in your photo. When installed above a subfloor, the PEX can either be installed in special subfloor panels with routed channels, or it's possible to pour a thin gypsum layer over the PEX.

    Is the floor in the photo possibly a concrete slab?
