The old code was my own suggestion, that I thought would just work, but
was also slightly skeptical about.
I tested out whether it works with the code below
```codeql
predicate foo(int input, string res) {
input = 1 and res = "that was one"
}
from int input, string res
where
input in [1, 2] and
if foo(input, res)
then any()
else res = "not one"
select input, res
```
which gave the 3 results
```
1 | that was one
1 | not one
2 | not one
```
only by rewriting the code to be the one below, did I get down to the 2
results I actually wanted. So I've done the same kind of rewrite in the
commit.
```codeql
predicate foo(int input, string res) {
input = 1 and res = "that was one"
}
from int input, string res
where
input in [1, 2] and
if foo(input, _)
then foo(input, res)
else res = "not one"
select input, res
```
