I think the key for me understanding and accepting this change is to decipher 
why:

"When the module is loaded again, a reload of res_pjsip is triggered which 
causes the observer to do a reload as opposed to a load of the file"

this happens. Why does a reload of res_pjsip cause the observer to perform a 
reload instead of a load?
