Nope,
Certain structural systems work best with one type of core or another. In this case their is a choice to use what is called a "Girder Slab" structure. This is a systems built to reduce floor to floor heights, which is useful if you might lower ALL the floor heights enough to squeeze one more floor in the zoning envelope. It has an inherent requirement to have diagonal bracing as part of the steel frame, so there is no real reason to make the core a shear wall (see other posts about what this is). That is not to say that one might choose to do both, but this system does not need it to be a solid concrete pour. They will likely use something much cheaper like gypsum shaft-wall.
