EIGRP auto summarization applies to the entire EIGRP process. The ip summary-address command let's you manually summarize that network only out of the applied interface. You could have a network out that interface that could be summarized but other routes in other places that can't be summarized.
So if you have some networks like 10.0.0.0/24 10.0.1.0/24 10.0.2.0/24 10.0.3.0/24,then auto-summary will advertise 10.0.0.0/8 to the neighbors ,,however io summary address eigrp 10.0.0.0 255.255.252.0 will summarize the 4 prefixes into one.and the EIGRP neighbor will have 10.0.0.0/22 in its topology table.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
