Oracle create index not in temp tablespace

Question

I have a great table with over 2.000.000.000 rows. Therefor i want to create an index on column1:

CREATE INDEX "SCHEMA"."INDEX_TABLE1" ON "SCHEMA"."TABLE1" ("STR1") 
PCTFREE 10 INITRANS 2 MAXTRANS 255 COMPUTE STATISTICS NOCOMPRESS LOGGING
STORAGE( INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645
PCTINCREASE 0 BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT)
TABLESPACE "USERS" ;

If i execute this my temp tablespace will be used and if its full (max 20gb) the creation will be aborted.

Where is my fault to create the index?

From Oracle documentation:

Creating a Large Index

When creating an extremely large index, consider allocating a larger temporary tablespace for the index creation using the following procedure:

Create a new temporary tablespace using the CREATE TABLESPACE or CREATE TEMPORARY TABLESPACE statement.

Use the TEMPORARY TABLESPACE option of the ALTER USER statement to make this your new temporary tablespace.

Create the index using the CREATE INDEX statement.

Drop this tablespace using the DROP TABLESPACE statement. Then use the ALTER USER statement to reset your temporary tablespace to your original temporary tablespace.

Using this procedure can avoid the problem of expanding your usual, and usually shared, temporary tablespace to an unreasonably large size that might affect future performance.
