This OM is Fervent Impersonation, where your Pokemon transforms into the nickname of your Pokemon if it is at or below 50% of its HP by the end of the turn.
On turn 19 in the first game, when my Blaziken switched in at 75% HP after a KO and took damage from hazards down to 50%, it did not transform despite being at 50% threshold required for transformation. At the end of turn 24 in a similar scenario in the second game, my Deoxys-Defense only transformed at the end of the next turn after switching in after a KO.
Clas, one of the council members, implied at https://www.smogon.com/forums/threads/fervent-impersonation.3740523/post-10061959 that end of turn damage, which can include hazards, should count towards the transformation.

This goes against the concept of the OM and is a bug.

Are you able to replicate it? If so, how?
Stack hazards onto your opponent and KO one of their Pokemon. Make them choose a Pokemon that will take enough damage from hazards to be at or below the 50% threshold for transformation.

I believe this is because that is how Zygarde's Power Construct works (which is what was referenced in the linked post).

Yes, but the issue is that the OM is designed to have the Pokemon transform if it has 50% HP or less no matter what at the end of the turn. Keeping this mechanic just creates unnecessary caveat to the OM that just goes against the OM's intention.
