  A recent article by Sassa et al. [Phys. Rev. B 91, 045114 (2015)] reports on
a soft x-ray angle-resolved photoemission study of MgB2. The analysis and/or
presentation of the collected data and the corresponding calculations appear to
be partially inconsistent. The aim of this comment is to provide a guide to
these inconsistencies and to discuss their influence on the presented
conclusions.
