You are right, in all of these boxes the context is relevant. I guess it
was left out because it was already said that all of these are in that
context.

The full line for P1@Ctx describes how P1 syncs: the Xmn boxes describe
how it access the respective source (basically the "sync" mode) and the
last column has the sync properties for the peer.

>From the perspective of the configuration system, "target-config" is
just another sync config and thus another line in the diagram. Nothing
stops you from setting a "sync" property in one of the Xmn boxes. But
these values are not used and therefore don't make sense there. Perhaps
this can be visualized like this:
| S1 | S2 | S3 |
----------------+----+----+----+-----------------------------
P1 | X11| X12| X13|P1 sync config properties
----------------+----+----+----+-----------------------------
P2 | X21| X22| X23|P2 sync config properties
----------------+----+----+----+-----------------------------
"target-config" | | | |target sync config properties
----------------+----+----+----+-----------------------------
|S1 |S2 |S3 |
|shrd|shrd|shrd|
|prop|prop|prop|
