Yes.

It acts just like the one I mentioned above. The general syntax is:

flags toolset var feature-spec * : value * ;

When values are not given it collects all the values previously given in the
target requirements. So that's the line that gets all places where you have
<include>/some/path in a target. The feature-spec can be rather complex, and
you can see that in the gcc-tools.jam where is picks out the option to
specify the CPU/architecture type.
