Subject: DBA_FREE_SPACE has multiple rows for a given file_id

I am an Oracle EBS DBA, who lurks here to learn. While looking at what one of our alerts do, I observed something that I felt strange.

Our in house DBA added a 2 GB datafile and it showed up as below.

It appears that the 2 GB was split into 496 MB x4 + 64 MB.

I'm curious to see why is there an upper limit of 496 here ? My SYSTEM tablespace has the below specs

Anyone with some free time who can help me understand is most welcome.

Thanks !! J
