Yes,it depends. The above mentioned effect is just my guess, the rationale is as follows:

1) Because the ssn is involved, a companion process may be setup to provide some tracking functionality.

2) The designer of the query process should let the user know that the event recording would be taken place as an effect of the query. 

I agree that the deatils is not important to this thread.
