Well I think they're talking about ensuring that the absolute difference 
between two floats is within a certain value (the epsilon).

I don't understand why it's called BOOST_CHECK_CLOSE for that reason, and 
COMPARE_FLOAT doesn't sound descriptive enough.  But epsilon is more of a 
computer science term and may be unclear to new programmers.  I still like 
epsilon better though.
