strange (?) ora7 behaviour using CTAS

list... this is something i cannot explain..

goal: to CTAS in a newly created tablespace

1. i created two raw devices test01 and test02
2. create tablespace test datafile '/dev/rtest01' size 1040m;
3. alter tablespace test add datafile '/dev/rtest02' size 1040m;
4. create table ratedlocal_test tablespace test storage(initial 1016m next 896 minextents 2 pctincrease 0 freelists 2) unrecoverable parallel 3 as (select * from ratedlocalcalls) /

when the table creation was going on.. i happen to look at the v$filestat numbers, i found
that the raw device TEST02 was being written to first !!! (it's the SECOND datafile in the tablespace creation)

my understanding is that when a table is created, the extents are
(initially) taken from the datafile which is
the first file when the tbs was created !!!

what could be the logic behind this ??
