Using major version would cause older daemons to reject those blocks as they fail to deserialize blocks with a major version which is not 1. There is no such restriction on the minor version, so switching allows older daemons to coexist with newer ones till the actual fork date, when most will hopefully have updated already. Also, for the same reason, we consider a vote for 0 to be a vote for 1, since older daemons set minor version to 0.
