> I'm trying to understand is why
This is actaully hard question to answer in terms of OSM right now. Why
does building exists? Why countries exists? We don't have answers for them,
but we map them regardless.
All I can say is that most cities in Russia use odd/even system as desribed
here ("European system")

Back to your question. I believe this is relevant to how governments manage
cadastre. For example when 2 old areas are united (owned by single person
instead of 2) then you have to deal with duplicate addresses. Similar to
buildings, when you have 1 single apartment building instead of 5-10
houses, you need to do something with their addresses. Thats why In the
middle of the street you may find address 13/17. But at street corners this
is different story. Sometimes we use double addresses, sometimes not. I
have idea why it is so.
Actually, try too hard to find any logic here, this is insane:
http://taginfo.openstreetmap.org/search?q=addr4: We don't have
cadastre logs or anything actually (only pictures of signs). We can only
guess why there only 4 addresses and not 5 or 2 or 1.
I have no knowledge about Czech descriptive numbers. I have no doubts they
do exist, but I have no idea why there need for them or do they relevant to
this addrN proposal.
Probably one day someone clever will deprecate old tagging schemes with new
one. Sadly, AddrN proposal is not about it.
