Recursive factorial function

Hi,

Trying my hand at recursive functions and found a simple recursive function for factorials and found this online :

Function myfact(num As Long) As Long
    If num = 1 Then
        myfact = 1
    Else
        myfact = num * myfact(num - 1)
    End If
End Function

I don't understand how this works. When num eventually reaches 1 won't the function return 1 instead of the complete factorial ?

Thanks,
