Yes, that number is the reactive power loss in the series portion of the
pi-model of the transmission line and it is a well-defined quantity. There is
also the line charging capacitance portion of the pi-model, which is a source
of reactive power. So whether the line consumes or produces net reactive power
depends on the parameters and the operating point.
I suppose how meaningful it is depends on what you are trying to make it “mean”.
