Yep. 

As for the stats contents, we do actually touch upon the question in basic probability. This is the reason that sums over infinite index sets are only defined if the corresponding sum of the absolute value is finite: Otherwise the result depends on the order of summation. (Think 0+1+2+(-1)+3+4+(-2)+5+6+(-3)+....)
