I think this is an overstatement. Relativity says that there is no
fixed frame of reference, so if one clocks move relative to each other,
it doesn't matter which. But this is refering to their POSITION (and
velocity).
Any side-effects, like melting because of passing near a sun, or losing
time due to a shorter path through space-time, would still be visible.
Relativity does NOT say that you will not be able to tell which clocked
move based on the CONDITIONs of the clocks.

Only because they don't understand it.
