Could this perhaps be due to S/360 systems being leased more often than 
purchased outright?  After all, the leasing system was one of the 
cornerstones of IBM's financial success.  Some hold the opinion that it 
was more important than any IBM technological innovation.

And, as far as I know, obsolete off-lease equipment was most often 
simply junked.
