Understand

It was previously shown that models with deformations of special relativity that have an energy-dependent yet observer-independent speed of light suffer from nonlocal effects that are in conflict with observation to very high precision.

In a recent preprint it has been claimed that this conclusion is false.
This claim was made by writing down expressions for modified Lorentz-transformations the use of which does not reproduce the result.
I will show here that the failure to reproduce the result is not a consequence of a novel and improved calculation, but a consequence of repeating the same calculation but making an assumption that is in conflict with the assumptions made to produce the original scenario.
