Why does sa_conn_properties() return a value of TempFilePages for the current connection that is wildly different from CONNECTION_PROPERTY ( 'TempFilePages' ) which should return the same value?

It may not be fair for the following query to call it "Incorrect TempFilePages" because (I think) it is a snapshot of the TempFilePages value when it has been momentarily inflated by the process of calculating the sa_conn_properties() result set itself.

HOWEVER, if that is the explanation, perhaps sa_conn_properties() could be modified to avoid using that inflated value.

SELECT @@VERSION,
       CONNECTION_PROPERTY ( 'TempFilePages' ) AS "Correct TempFilePages",
       Value AS "Incorrect TempFilePages"
  FROM sa_conn_properties()
 WHERE PropName = 'TempFilePages'
   AND Number = @@SPID;

@@VERSION,Correct TempFilePages,Incorrect TempFilePages
'12.0.1.3810','14',794
