Because the lawyers demanded it -
COMICS SCENE MAGAZINE was a mainstay of the STARLOG empire, not least because its fortunes waxed and waned through several runs depending on the public's overall interest in comics and their characters.
The mag was initially announced and promoted as COMICS WORLD (a title that would later become familiar with British collectors thanks to an entirely different magazine with a very similar - but not identical - title) but that fell victim to some sort of legal shenanigans/ prior title claim and had to be changed prior to the first issue hitting the stands.
After a quiet few months (during which time the collective Starlog brains trust must have been frantically brainstorming alternatives... and making sure fandom hadn't already thought of them) they bounced back with... COMICS SCENE. Hurrah.
