Well, maybe not a lot of people have asked for this but from a standpoint of character development and filling some holes out there, it does its job.
This little slice of life story basically gives the spotlight to Ocellus, who hasn´t received a single episode in the show (understandably so because the cast was already big before the students were introduced) and yes, it exposes both the students and the school for them.
As shown in 2,4,6 Great, Ocellus has always wanted to do something else instead of changing forms and scaring in the public eye, leading to some confusions and having some regrets of having only that feature (that´s why she joined into cheerleading and do something different). Here, we deal with that unique aspect again: how disguising into others can become productive.
Ocellus hasn´t shown herself as a nerdy student in the past and here, the midterm presentation becomes from a chill out activity to a stressful task for her, just because in less than 10 minutes, she intended to transform herself into 346 entities. This explains why characters like Celestia, the pillars,Sombra and Chrysalis are shown in this comic: >>5016,>>5022,>>5025 and >>5026.
All of this came from her personal will and she took it to really extreme levels of perfection and that becomes evident when she reaffirms her ideas in front of Silverstream (Page 10):>>5021.
