It is not that love is different, that there is one love for the Lord and there is another type of love for devotees of the Lord. No, when we love the devotees of the Lord and we want to serve and please the devotees of the Lord, our mentality should be that by serving this devotee and not expecting anything in return, we are actually satisfying the Lord. This is our way to please the Lord.
