The pad in question is the one from the song's beginning.
I detect qualities imprinted by effects such as chorus and panning, but I can't just get that genuine tone that stands out, in subjective terms as warm but also a bit metallic. Using a sine oscillator for these chords renders a dull result, failing to provide that subtle movement emphasized by the chorus, with pulse width oscillators rendering a "nasal" sound.
I also think he's playing power chords, i.e. root + fifth sustained, or root + fifth + octave. What does the community think?
