It has bitten me more than once. Mainly because I was not formally trained in any languages that used curly brackets (FORTRAN and ADA). If an IF statement doesn't have curly braces, it looks natural and just add more to it. If an IF statement does have curly braces, they are there for a reason and add stuff between the braces.

Of course, I am probably not the kind of person that would ever get hired with Tony's employer.
