I don't fully grasp the reason for this.

is the parameter type and point
is the parameter name. The name could have been anything, it doesn't have to be point
. But the type has to be Point
because that is based on the class name.
You are telling C# that you are expecting to be passed a Point
object and that it should be assigned to a variable called point
. It is the same as if you set up a method that was expecting a string
or an int
. Except that instead of using built-in datatypes you are using a class you created yourself, which is also considered a type of data in C#.
While it can be confusing for beginners it is pretty common to name variables that will hold an instance of a class the same as the class itself (just in lower camelCase), though as I mentioned above that is not mandatory. You can use whatever name you find appropriate.

7,736 PointsYou stated Java instead of C#, but the same is true for both languages I believe. I'm going to definitely upvote this answer.

28,558 PointsOops you are right, I often answer Java questions on this forum so that was a typo on my part. Thank you for pointing that out to me, I have now corrected the post.
And it is indeed the same in both languages. Java and C# are quite similar at least as far as the basics of the languages are concerned.
