multiphase DyM solvers - velocities

I'm dealing with interDyMFoam and compressibleInterDyMFoam for quite some time now. At a recent meeting, the question came up which velocity is calculated - relative or absolute.
In this specific case, a closed test tube filled with 50% liquid and 50% air will be "shaken" along the longitudinal axis according to a prescribed oscillation (non-sinusoidal).
Looking at lines 110 and 111 in compressibleInterDyMFoam.C, I find
// Make the fluxes relative to the mesh motion fvc::makeRelative(phi, U);
Maybe, someone is able to shed light on that matter. Thank you
