Raw polynomial is reported as orthogonal

The Problem
I trained a recipe to be have raw polynomials, but when I print it out, it says it is orthogonal:
Reproducible example
library(tidymodels)
library(tidyverse)
data(biomass, package = "modeldata")
rec <- recipe(
HHV ~ carbon,
data = biomass
)|>
step_poly(carbon,options = list(raw = TRUE))
quadratic <- prep(rec, training = biomass)
quadratic
#head(biomass_tr|>select(carbon))
#head(quadratic$template|>select(starts_with("carbon")))
