There seems to be a mistake in the example given in the explanation.
"Because all an if() needs is a boolean, now b1 != b2 returns false which is a boolean and as b2 = false is an expression and every expression has a return value (which is actually the Left Hand Side of the expression). Here it returns true which is again a boolean."
The last statement in the above 'Here it returns true which is again a boolean.' is not correct as
'if(b2=false)' will result in false (and not true) as it is an assignment.
