Maybe what matters isn’t the proximity of the caster but of the patronus itself. Though Harry might still not be able to send his 2.0 on a search&destroy mission while staying at Hogwarts.
His wand stayed in his hand, and a slight, sustainable flow from him replaced the slight losses from his Patronus.
There seems to be a need for constant energy transfer into the patronus, and I doubt this transfusion line can go through hyperspace.
