In particular the rocket system that landed was discarded and a new rocket system took off, so I don't think it's even "technical". It's like calling a car that rolls off a ferry an "amphibious" vehicle.
Eh, if you could make a DUKW that, upon reaching land, could (or had to) shed its hull and become a proper vehicle of some sort, I'd still call it amphibious.
> Hell, the Apollo Lunar Module technically landed and took off afterwards, as well!
It landed and launched in a relatively airless (windless) environment at 1/6th Earth's gravity ... and when it launched it left half of itself behind!
"Technically" indeed.
