Is there in error_log error something like "listen(127.0.0.1:80) failed (98: Address already in use)" ?

No. Your first configuration is

server {
   listen *:80;
   server_name  one.local;
}

server {
  listen 127.0.0.1:80;
  server_name  two.local;
}

A client connects to 127.0.0.1:80, so nginx uses the second server to processes request.
When you change listen in the first server to 127.0.0.1:80, nginx has two servers for this
listen port and chooses server using "Host" header.
