the multiple log files will be addressed as one sequential topology, but importantly If the log contains multiple physical log files, the logical log will move through all the physical log files before it wraps back to the start of the first physical log file. So all the files act as one wrap around file.

The logical file being where the active vlfs start to where they end.

How long the secondary takes to clear and cantherfore be dropped will depend on its size and level of database activity.

you'll be wasting your time shouting at MS, its designed like that to be simple and robust, its got to be simpler than oracles redo logs 🙂
