Because the song is all about their missing member, making it a quasi tribute song which to me says "he's here in spirit, he just needs some help"...the rest of the album doesn't feature Malik in lyrics or in spirit, so I think that's what the OP was getting at.

I get what you're saying, don't get me wrong. I just look at the song from the other perspective.
