Such is close to what I have always understood about receive, but the
confusion is that the second receive command makes no reference to the
subvolume created by the first command. How do I ultimately create a
restore target that combines the original full capture with the
incremental differences?

When I ask how I use it, I mean what commands do I enter into the
system.

Note in my case I archive the streams into regular (compressed) filesm
for later recovery.
