A hot backup is one done while the database is up and the users are making changes during the backup, unlike a cold backup – the database is shutdown and no changes are made while the backup is running.

Yes, but the reason why they are considered inconsistent is because, with the database open, there is no guarantee the the data files are synchronized with the control files.
