It's got nothing to do with ambiguity, you're fundamentally thinking about dot notation wrong. The dot notation is the actual naming convention, not using it is a convenient shortcut. Many professional programmers would chew you out for not using it, being lazy and leaving it off can easily introduce unintended bugs. For example, you add a new column to a table, and boom, half your SQL statements now fail because it's got the same name as an existing column on another table.
