In a very recent work, [1] claim that the scenario of temperature inhomogeneities proposed by [2] (t2 > 0) is not able to explain the O2+/H+ abundance discrepancy observed between the calculations based on the optical [OIII] collisional excited lines (CELs) and the OII recombination lines (RLs) in the star forming galaxy Mrk71. In this work, we show that conclusions of [1] depend on several assumptions on the absolute flux calibration, reddening correction and the adopted electron density. In fact, using the data of [1] in a different way and even considering their 1{\sigma} uncertainties, it is possible to reach the opposite conclusion, consistent with t2 = 0.097−0.009+0.008. Therefore, the existence of temperature inhomogeneities causing the O2+/H+ abundance discrepancy in Mrk71 can not be ruled out.
