Could someone please help me understand this

restart;
expr:=(A*x-1 )/x
eval(expr,x=infinity)
    # 0    why?

limit(expr,x=infinity)
   # A correct

How did Maple evaluate expr to zero when x=infinity? What math did it use to obtain this result? Did it may be just saw infinity in denominator and said the whole thing therefore is zero?  But there is infinity in the numerator also and infinity/infinity is not defined.
