English: “A male goat” — not a bull; “on the horns of the olah altar” — the outer altar, not the inner. The nasi’s chatas is an outer chatas, like that of an ordinary individual.
In Sifra: Rank drops from the two inner-bull cases (anointed, Sanhedrin) to a male goat whose entire blood service stays at the outer altar. The nasi is closer to the individual than to the anointed or the court.

What Is Learned
The nasi brings a male goat processed entirely at the outer altar; he does not share the inner blood service of the anointed or the community.
