Justice and Rule
Legend
None of which changes the fact that they have different entries in the book and different stat blocks. It's kind of like saying that a 5E guard is the same as a champion because they're both human.
Different stat blocks means nothing. My character at 1st level has a different stat block than my character at 15th level. What matters is that in the fiction they are the same; the difference in the stat blocks comes from the progression between the two moments.
The same can be said for the ogres. Those stat blocks could literally represent the same ogres, but at different points in the story. It represents where they are relative to the players: they could potentially keep up with them, or they could fall behind them. But it doesn't change that, in the fiction, they're still the same ogres.
