Hi Greg,
the z(@geometry) function as well as both x(@geometry) and y(@geometry) 
functions always return the actual geometry's x, y, z coordinate 
regardless of the layer's CRS or the project's CRS.

I.e. @geometry (or the deprecated $geometry) returns only a geometry 
object that doesn't contain any info about the CRS.

Best regards.
