backup and recovery question

Our system administrator brought up an interesting point:

I know that a backup of Oracle files for a open database in NOARCHIVELOG mode will not startup the database. However, I was not able to give a good explanation for the following question:

What is the difference between a
database started after a machine crash due to a power loss and a database started with all Oracle files copied at exactly same point in time for a database running in NOARCHIVELOG mode and when the database is open.

Would an Oracle instance recovered using these set of files perform an instance recovery at startup?

Thanks..
