The example provided is fairly worthless without a context.
Using the private command allows you to declare a variable in the current scope, without regards to variables in a higher scope with the same name. Note that if you try to declare a variable without an underscore (meaning it's global) with the private command, it will cause an error. Specifically: "Error Local variable in global space".
Here's a code example with output for your benefit.
_foo = 10; if (true) then { private ["_foo"]; _foo = 5; player sideChat format ["%1", _foo]; }; player sideChat format ["%1", _foo]; In this example, the first sidechat (innermost) returns 5 while the second sidechat (outermost) returns 10.
if (true) then { private ["_bar"]; _bar = 5; player sideChat format ["%1", _bar]; }; In this example, the private command does nothing and is simply a waste of code, assuming there is no higher level code to interfere with the if statement.

The higher scope is also the script from which the function has been called.
If you've got in the script: _a = 1; call compile loadFile "function.sqf"; hint format ["%1", _a]; And in the function.sqf: _a = 2; Game will display 2.

Inserting private "_a" in the function prevents the change and so number 1 will be displayed on the screen.
