st: why -if- does not work in -expandcl-?

Dear statalists,
I found -if- did not work in the -expandcl-.
For example,
. clear
. input x y
x y
1. 1 1
2. 2 1
3. end
. expandcl 2 if x==1,gen(new) cl(y)
(2 observations created)
. l
+-------------+
| x y new |
|-------------|
1. | 1 1 2 |
2. | 1 1 1 |
3. | 2 1 2 |
4. | 2 1 1 |
+-------------+
Why also expand when x equals 2?
Hope for any help.
Regards,
Grace
