multiple ospf process redistribute

[fly]

Hi, 

   I read this document

   http://www.cisco.com/c/en/us/support/docs/ip/open-shortest-path-first-ospf/4170-ospfprocesses.html

  below figure 4, i have question after //

1. Router A (Router B) redistributes M into Domain 1, and external M will reach Router B (Router A).

2. Because the administrative distance of Domain 1 is lower than Domain 2, Router A (Router B) will install M through Domain 1 and will set to maxage its previous originated LSA (event 1) into Domain 1.//what's this LSA,the redistribute from another doman?

3. Because M has been set to maxage in Domain 2, Router A (Router B) will install M though Domain 2 and, therefore, will redistribute M into Domain 2.  //event 2 said maxage in Domain 1 , now it is domain 2. i confused?

4. Same as event 1.

   thank you!

in event 2: cisco website say set maxage its previous orginated LSA into Domain 1.

but in event 3: say because M has been set to maxage in Domain 2??????

is this a mistake?

when router A receive M type 5 lsa from its domain 2，and redistribute M into domain 1，router B also redistribute M lsa，and will receive lsa from router A，because lower distance，so router B will choose lsa from router A（domain 1）， and maxage its origin lsa。

so inside domain 1，only one lsa from router A exist， is that right？

but inside domain 1， which one（router A orB) lsa can exist,  we can't control

depend on the status of ospf process running?
