RE: Clarification on DISTANCE command

Hi,
As far as I remember when doing it previosuly that the multiple distance
commands are scanned by the router sequentially
so for the 1st example the distance of all ospf routes learned will be 255
and hence not in the routing table, thus the next 2 distance commands are
not used

In the 2nd example distance 90 for all routes from router with router-id
a.b.c.d (mask w.x.y.z), distance 120 for all routes from router with
router-id e.f.g.h (mask w.x.y.z) and distance 255 for all other ospf routes
learned from all other routers.

Hi group.
Can someone eloquently explain the practical difference between these
two?
 
Example 1:
Router ospf 1
Net a.b.c.d
Distance 255
Distance 90 a.b.c.d w.x.y.z
Distance 120 e.f.g.h w.x.yz
 
Example 2:
Router ospf 1
Net a.b.c.d
Distance 90 a.b.c.d w.x.y.z
Distance 120 e.f.g.h w.x.y.z
Distance 255
 
TIA.
