   Your point well taken but with the steinway did you have the strings off??
I suspect it  probably would have come back to at least (or mostly )flat. The 
sohmer didn't budge and it was so uniform. I;ll add that it did have modest 
positive crown.
      Also we know that steinways  at least have the intention of a positive 
crown. And it would seem so with most of the sohmers reported on so far as 
well.  I'm  guessing this was a factory experiment or a short lived run.
       The condition you saw in the Steinway ( happens infrequently) I 
believe is caused by uncontrolled R.H. at the time of  pressing on the ribs. 
Too wet at glue up, Installed in the case too swollen,  too wet when bearing 
was set. and bearing set too heavy. Coupled with extreme panel shrinkage 
later , poof instant salad bowl. Same thing could the case with the Sohmer in 
question but I have doubts.
 I once rebuilt a stwy A -2 that had a trough where the bridge was, a flat 
board,still positive and evenly set risidual bearing and the darn thing 
sounded amazingly good. This was partly because of the support of a fairly 
thick soundboard to start with.
