It's been a while, but my recollection is that the most significant load is the side-to-side motion, so it seems plausible that a piano could be tipped over.   Also, we had to hire an engineering firm, licensed in the state of California, who analyzed and approved our design.  You should separate yourself from any design responsibility here.  If the church has gotten some engineering authority to say " if you chain it this way, it will be safe", then go ahead and chain it exactly the way they tell you to.
