I agree with your line of thinking = some pulley is "pulling or pushing" the wrong way.   The only pulley that is loosened in the process is circled in yellow.  It seems to be ok and the two nut process tightens the belt good.  In looking at the whole thing it seems to me that that alternator (in square green) is slightly off.  But I cannot easily see how an adjustment could be made.  So I lean toward calling in the folks who know what they are doing,
