I think "that doesn't make sense" will be unavoidable for some narrow
meaning of "sense" for some combinations of keypresses in mixed L2R-R2L
settings.

For me, the behavior makes perfect sense, and is, in some manner, even
telling us something beautiful about the structure of texts, just like
the equations of Special Relativity as opposed to the equations of
Newtonian mechanics "don't make sense" in some view, but tell us
something beautiful about the structure of spacetime.

We really should not try to define "makes sense" in terms of relations
that arise from fundamental properties of unidirectional text.
