The energy loss is due to the various energy-loss physics processes, not due to steplimit. But steplimit is listed as the process, because it limited the length of the step. The energy-loss processes always apply their energy loss, regardless of which process limited the step length.
Statistically, the energy loss of tracks in a given volume/material is almost independent of the step limit imposed on them. (You cannot compare them track-by-track, as different step limits will cause different random numbers to be used for each track.)
The attachment shows the effect of maxStep on the energy loss in 30 cm of liquid hydrogen; the plot is the final kinetic energy of 200 MeV/c mu+ (initial KEmuon = 120.5 MeV). A 100 T solenoid magnetic field (!) does not affect the plot significantly.
