  Li et al. (2018a; Li18a) claimed that the young stellar cluster NGC2173 in
the Large Magellanic Cloud (LMC) harbours a bifurcated sequence of blue
straggler stars (BSSs), similar to those detected in a few dynamically old
globular clusters. However, Dalessandro et al. (2019; D19) re-analyzed the data
by taking into account the contamination of the cluster population from LMC
field stars, which was completely neglected by L18a. D19 showed that $\sim40\%$
of the selected BSS sample (and especially the population observed along one of
the two sequences) is composed of field star interlopers, concluding that the
double BSS sequence is most likely a field contamination artefact. In a recent
note Li et al. (2018b) argued that the analysis by D19 is affected by two
issues related to (1) the use of different HST instruments/filters in the
decontamination procedure, and (2) a presumed overestimate of the number of
field stars, which show a central radial segregation. Here we demonstrate that
the D19 decontamination procedure is completely unaffected by the use of
different HST instruments, and that, the field stars removed by D19 have no
significant radial segregation toward the cluster center. Hence, we confirm
that the claimed double sequence is just a field contamination artefact.
