1) he didn't: there was only one column
2) we allow duplicated column names
 For example
 gives a data frame with two columns having the same name. What do you
think they should be called?  
We discussed this some time ago in the context of offsets in glm(), and
model.offset contains code to handle multiple "(offset)" columns.
