Question about log files

Reading the DBA manual in the chapter 7 refers that  

• When an online redo log file group is dropped, the operating system files are not deleted.
• When an online redo log file member is dropped, the operating system file is not deleted if you are not using OMF feature.

What happens when drop the log file group if using the OMF feature, the files will be deleted
also ???
