possible redundancy in BBB dts file?

crawling my way through the BBB dts and dtsi files and just want to
make sure i understand the relationship between included files. here's
a snippet from am335x-bone-common.dtsi:

                ldo3_reg: regulator@5 {
                        regulator-name = "vdd_1v8";

and from the top level BBB dts file:

&ldo3_reg {
        regulator-min-microvolt = <1800000>;
        regulator-max-microvolt = <1800000>;

  i'm *assuming* that since the included file already defines the
property "regulator-always-on", defining it again in the BBB dts file
is superfluous, correct? or is there something here i'm missing?
