concurrent mode in svn

I want to learn more about concurrent mode in SVN.
I found quite contradictory facts.
SVN uses copy-modify-merge solution that allows users see if a file is
out-of-date (modified by someone else). At the same time, another site
claims that SVN does not have that ability which leads to unavoidable
conflicts especially with binary files.
What is true?
