[ambiguous occurrence bug?]

Sorry in advance if I should be posting questions of this kind elsewhere
(please tell me if so!).
Consider this two file program:
module T where
main = undefined
module Main where
main = putStrLn "Hello world!"
Both 8.4.3 and 8.6.3 agree:
Ambiguous occurrence ‘main’
It could refer to either ‘T.main’,
imported from ‘T’ at Main.hs:2:1-8
(and originally defined at Main.hs:2:1-4)
or ‘Main.main’, defined at Main.hs:5:1
Is this expected behavior? Does it not contradict "If the export list is
omitted, all values, types and classes defined in the module are exported,
but not those that are imported" (
https://www.haskell.org/onlinereport/haskell2010/haskellch5.html)? If the
latter, is this a bug? What am I missing?
