The idea in the code was to protect the user that tries to connect a slave to a master with completely different domains than what was intended. If none of the domains in the start position are present at all in the master binlog, we gave an error. However, this is a stupid idea. Because when a slave connects to a master to start replication from the very start of binlogs - such as when setting up new master->slave servers from scratch - there will be just this situation, the requested slave position is empty for all the domains in the master's binlog. So the code that gives this error is wrong, and the solution is simply to remove it.
