Not sure what he thinks but here's what I think. Although the verticality thing isn't bad in and of itself (it does look nice) it effectively gives you less space on the screen which encourages usage of space saving measures like one letter variable names and abbreviations. This makes it difficult to understand your intention and may make it difficult for someone else to take over your project.
