Is there any reason to write set { value = num; }?

Question

Is there any reason instead to write
set { num = value; } / set { value = num; }

public class SomeData
{
private int num = 1;
public int numGetSet
{
get
{ return num; }

set
{ value = num; } // { num = value; } can also be written
}
}
void Start () {
SomeData sNewData = new SomeData();
int num1 = 2;
sNewData.numGetSet = sNewData.numGetSet + num1; // Output is: 1

i just ask because i switch by mistake
set { value = num; } // { num = value; }
and i was a bit surprised, that this way is also working ...
Cheers
