We correct erroneous conclusions from Ref.[1] regarding the values of various critical exponents, calculated to the two-loop order, and argue that ϵ-expansion near two spatial dimension, with ϵ=d−2 may not be reliable to address the critical properties of disorder driven Dirac semimetal-metal quantum phase transition in d=3.
