Oracle DB: Can one db file be shared between table space Can one db file be shared between table space?

I am deleting temp table space as below, 


Get all the files in  table space: 

SELECT FILE_NAME  
FROM DBA_TEMP_FILES 
WHERE TABLESPACE_NAME = 'TEMPRM_TEMP'; 

Drop all the files in the table space:

ALTER TABLESPACE TEMPRM_TEMP 
 DROP TEMPFILE '/tmp/TEMPRM/create/TEMPRM/datafile/o1_mf_temprm_t_bw3yo9lv_.tmp';

Drop the actual table space: 

DROP TABLESPACE TEMPRM_TEMP INCLUDING  CONTENTS AND DATAFILES;



Are there any harm with this procedure ?
From the Oracle 11g Documentation:


  A datafile can be associated with only one tablespace and only one
  database.


So you don't have to worry about losing data from another tablespace.
