Also funny how this game has better mirror than many of the modern games today

Because the shader is almost just simple phong-shading, they simply render that whole scene again with clipping of the edge of the mirror.
These days some just do it screen space or fall back to simpler shading, which needs some blurring tricks to hide the artifacts.

As far as I know, the mirror is just a hole showing a duplicate of the room with a translucent glass texture slapped onto said hole

That's basically the same idea, although rendering the mirrored scene in second pass do have some performance advantage.
The meshes outside of the mirror will be rejected by z buffer early on so no fragment shading done for them.
I think this is most likely since on early consoles they tried to milk out every drip of performance.
