That's like saying kamehameha, super kamehameha and bending kamehameha are all different attacks just because they are used differently. Star Flash and Star Flash Supernova are both fired by the same character, has the same color, the same impact shape and effect, the latter is just a different upgraded version of the same attack, that's apparent by the name itself.
Even if you argue that since there are some dissimilarities in both of them, which is okay, that still doesn't take away from the problem of the statement not being matter of fact. In the thread made about light standards previously, it was clearly explained that the fourth standard should definitely suggest that the attack is made of photons/composed of light, from a reliable source. "Beam of light" is such a common statement that it needs to be coming from a reliable source in a reliable manner. If a scientist claimed "this energy ray transmitted from this weapon is a beam of light" then that would have been an acceptable case.
A character going "The villain shall be defeated by a hero's beam of light" is not an acceptable case. You can argue about it all year long and the statement would still not be a reliable one because of the way it is delivered.
