That's exactly what he's saying.

The addresses here are typically not for a part of the building but for 
the whole building, or actually for land area it's in (lot? parcel? or 
whatever would be proper English word for that land), so it could cover 
even more than one building. And then a totally separate "address space" 
for the apartments is combined to them to get the "full address".
Apartment address space typically follows letter+number scheme. That gives 
you 1ststreet numberX A 1 and 2ndstreet numberY A 1, etc. for the very 
same apartment! ...This is not an exception but very very common here 
(addresses are assigned for all streets a lot/parcel is touching so it 
happens in practice at every road intersection). Officially none of them 
is given priority but in many cases people tend to use one of them more 
than the others. However, I've seen cases where the addresses given to 
subscription systems were automatically reassign to another ones for the 
delivery (more than once, I suspect it could be some delivery route 
optimization feature).

In addition to that, we of course have buildings with different addresses 
sharing a wall in packed areas which was probably what you meant with 
"you have this almost everywhere"? However, again those adjacent buildings 
could have here more than one address each.
