https://dev.mysql.com/doc/refman/8.0/en/binary-log.html says:

A binary log file may become larger than max_binlog_size if you are using large transactions because a transaction is written to the file in one piece, never split between files.

This means if you change many rows in a single transaction, or the rows contain very large data values (e.g. long BLOB or TEXT content), a single binary log could grow far past the supposed limit on the size.
