Ask about BULK COLLECT in 10.2

Hi all,

I read title about "Using BULK COLLECT with Queries" and there is short document said that:

As a result, you do not need to explicitly convert your cursor FOR loops to use BULK COLLECT if:

 + You are running 10.2 or higher.
 + Your optimization level is to 2 or higher.
 + The cursor FOR loop does not contain any DML statements (insert, update, delete).

So, I'm using 10.2. If I open a cursor and FOR loop not BULK COLLECT, this code 's perfomance is same as using the BULK COLLECT ???
