Its the other way around. No chance that the drawings show 11' and the formworker/GC is trying to "save time/money" to form 9'. That just doesnt happen. Plus they have Verdi on this job who would form 20ft without question.

Sales/marketing gets details about floors from construction. Someone made a mistake or didnt properly check the drawings. It could have been clearly shown or there could have been a transfer slab that would not be picked up by some office staff at the sales/marketing stage.

Actually it happens quite often that subtrades propose changes in exchange for credit.  Especially the big structural trades. Obviously the forming company could do whatever is drawn but there is definitely time and financial savings by keeping as many floors typical as possible.  Plus those 4th floor podium suites wont sell for big bucks like the penthouse units so the 11' ceilings could have been scrapped before construction began and the change failed to make it to the marketing team. 
Either way even if I'm wrong or you know something I don't,  it sucks for the person buying a unit that thought they were getting high ceilings.

Imo there was no actual change, someone saw 11' concrete to concrete height on drawings but it was meant to be a mech crossover flr or a thicker strucural transfer slab and a 9' finish height was always intended with a drop ceiling. And yes 11' is unheard of for condo unless high end penthouse levels. Looking at the pics of the podium there is def higher floors due to a heated soffit where the suites above overhang.
If its on the 4th flr podium you arent typical yet so that would not change anything on time/schedule. Trust me forming company would not be involved in anything like this.
