no, in reality it saves 1.1GB, here are the details

the file sizes from alex email above

560M    org.freedesktop.Platform/x86_64/1.6/
796M    org.gnome.Platform/x86_64/3.28/
1.1G    org.kde.Platform/x86_64/5.9/

total of 2.4GB

sizes considering shared files

560M    org.freedesktop.Platform/x86_64/1.6/
253M    org.gnome.Platform/x86_64/3.28/
542M    org.kde.Platform/x86_64/5.9/

total of 1.3GB,
saving is 2.4-1.3=1.1GB
