I have not come across exceptional less reactivity of p-xylene. Two electron donating groups are there, so the ring is activated, wshould lead to formation of one product as both the groups are o-p-directing and with p-position blocked.Thus there appears no reason why p-xylene should be less reactive towards SE reaction.
