For military uses, such capabilities would allow reconnaissance satellites to keep station over specific areas of interest and tank up on vital propellant later

That staff writer should be fired. No satellite can “keep station” over a specific area of interest unless it’s in geosynchronous or geostationary orbit - and even those are limited to within a couple of degrees of the equator. I would expect a writer for space.com to know, at the very least, the basic fundamentals of orbital dynamics.

I think what he meant to say is that the ability to refuel spacecraft could permit reconnaissance satellites to adjust their orbits to optimize revisit times over certain areas of interest - and that is a cool ability in and of itself.
