Alexander understood that having Rachel by Michael's side was better for his moral support. He saw how his father was happier, he smiled more, he talked more, it was like a side of him that was buried this whole time emerged again. So, Alexander made the decision to move back to his penthouse.
The reason he lived in the mansion in the first place was to take care of Michael. Now that Rachel was there to take care of it, he can step back and let the couple spend more time catching up and mending their relationship. He still visited and called to check up on Michael's health regularly.
