So you assert that setting a spear is readying an attack?
Bearing in mind that several weapons that can be set to receive a charge are not reach weapons (halberd, spear, urgrosh), it seems that setting a weapon to receive a charge requires a readied action of the form "If he charges me, I hit him".
1a. Attacker has a longsword, Defender has a spear. Defender readies an action - setting the spear against a charge. Attacker charges; when he moves into the adjacent square, the Defender's readied action triggers, and he strikes with the set spear for double damage.
1b. Attacker has a longsword, Defender has a spear. Defender readies an action - setting the spear against a charge. Attacker takes a move action to approach, and attacks; when he moves into the adjacent square, the Defender's readied action does not trigger, since he did not charge.
2a. Attacker has a longsword, Defender has a spear. Defender readies an action - attack when the Attacker approaches. Attacker charges; when he moves into the adjacent square, the Defender's readied action triggers, and he strikes with the spear, but since it was not specifically set against a charge, there is no double damage.

So setting the spear has the advantage of doubled damage, but the disadvantage that it can result in a wasted action if the attacker does not charge. Readied a generic attack-vs-approach has less possibility of wasted action, but will not result in doubled damage.
