Though probably not the original reason, I would say it's still useful as it brings some kind of distinction between keywords and variables/columns, since SQL consists mostly of words with less punctuation than other programming languages.
Consider:

```
SELECT name FROM animal LIMIT 10
```

which contains only spaces as non-alphanumeric characters.

vs

```
animal.filter(limit=10)
```

containing a dot, a pair of parentheses and an equals sign as non alphanumeric characters.

Of course, there's syntax highlighting to show the distinction, but I think caps still add something.
