The consistency that they're referring to specifically is to do with consistency in the way that certain features or functionality is implemented.

To make your example match, it would be more so that there are two teams A and B, Team A already created a framework and integration for logging across the entire application. Team B comes along and doesn't realize that this framework exists, and also invents their own framework and integration for logging.

This is the type of consistency that the author points to, because Team B could have looked at other code already referencing and depending on the logging framework from Team A and they would have avoided the need to create their own.
