The results published by O. Yamaod and W. Sintunavarat in [On new orthogonal contractions in b-metric spaces, Intern. J. Pure Math., ۵,  ۲۰۱۸, ۳۷--۴۰], and by K. Javed, H. Aydi, F. Uddin and M. Arshad in [On orthogonal partial b-metric spaces with an application, J. Mathematics (Hindawi), ۲۰۲۱, Article ID ۶۶۹۲۰۶۳, ۷ pages] are discussed. First of all, some formulations that are not precise in these papers are commented. Then these results are extended and unified from the case of orthogonal b-metric and orthogonal partial b-metric spaces to the wider framework of orthogonal b-metric-like spaces. Moreover, some results are generalized by proving that the contraction parameter may belong to the wider set [۰,۱).
