NYguy is correct, the "entire" side of the Yale building was always visible, historically as well even before the vent building was built in place of the former building that occupied its footprint.

The only difference now is that more of the Yale club building's lot wall will actually be hidden now. To JSsocal's point, per the renders, most of the 44th St massing holds to the property line, it's just a small portion that is recessed that joins the rest of the setback massing above the podium portion that reveals the Yale club's side.
