All route entries learned through EIGRP will be in the EIGRP topology table. You may not be able to see them using the command show ip eigrp topology. One way to see all entries is by using the command with network information as you did: show ip eigrp topology x.x.x.x/y. The other alternative is to run show ip eigrp topology all-links.
Meheretab is correct that all learned EIGRP routes are entered in the topology table. The original post suggested a definition of routes to be entered in the table
the advertised distance had to be less than the feasible distance of the successor
This is the definition of feasible successor route and not the definition of what would be entered in the topology table.
I hope you are having some miss understanding of some typical words of eigrp.
The topology table will store all learned EIGRP routes.
