Why are these things "pushed" as "midair" printing techniques?

Why are these things “pushed” as “midair” printing techniques? they all start from a baseplate and, since they are metallic (thus have very good structural integrity while solid) and don’t need supports, they can be printed at odd angles. OK, that’s all nice and good (size reduction brings even more stability to the structure) but why call it “midair” ?

Definitely not printed in “mid-air” - just more over hyping of a modest improvement…
