I find that doesn't really capture the difference. In programming, the building part is fully automated. You press play or type a compile command and wait. If someone wants a build estimate, you should give them the time it takes to compile an deploy. Code is blueprint. Writing the code is all engineering, R&D, design and architecture and it usually entails figuring out how the system will interface with countless protocols, legacy systems, details of user's lives etc. It's nothing like building something that is already fully planned. It's a lot more like researching and planning all the details.
