We thank the Belgrade SNR Research Group (called ‘supernovashi’), the results mentioned here belong to all of us: B. Arbutina, B. Vukotić, D. Onić, M. Vučetić, M. Pavlović, V. Zeković and P. Kostić. We would also like to thank D. Ilić and A. Ćiprijanović, our internal collaborators who are mainly based in other fields of astrophysics but work with us on much of our research on emission nebulae. The concept suggested in this Comment would never have been tested on observational data without M. Filipović, our main external collaborator. Finally, we extend many thanks to M. Božić for exciting discussions and careful editing of the text. Additionally, we acknowledge the financial support of the Ministry of Education, Science, and Technological Development of the Republic of Serbia.
