在使用tikz的intersections library的时候产生了一个疑问，如果有两个以上的交点时，这些交点的顺序TikZ是如何判断的，比如下面代码的例子，此时intersection-1是上面的那个点，而换成intersection-2就是下面的那个点，这是如何判断的？ 非常感谢！

\usepackage{tikz}%调用tikz宏包作图
\usetikzlibrary{intersections}%应用此 library 找到两条曲线的交点
\usetikzlibrary{calc}%in order to use the coordinate calculation functions
\usetikzlibrary{through}%this library defines keys for creating shapes that go through given points
