The Nagari continued the bottom stroke to make a circle and enclose the 3-look-alike, in much the same way that the sign @ encircles a lowercase a. As time went on, the enclosing circle became bigger and its line continued beyond the circle downwards, as the 3-look-alike became smaller. The Arabs simply connected that squiggle to the downward stroke at the middle and subsequent European change was purely cosmetic.
