Has that changed? At WWDC 2012 (as I remember), one of the big features of iOS
6 was that so long as you kept your file names consistent (there were a few
slides on how to do that), App Store downloads would be incremental.
Incrementally downloading new and revised files doesn't stop the installer from
removing the deleted ones.
This is a separate issue from merging the download and the (surviving) existing
files into a fresh application bundle, transferring the user's files and
preferences, and swapping the new bundle in. As far as I know, that's still
what happens, but it's orthogonal to whether the download is incremental or
from-scratch.
