Does BETWEEN with dates actually work in SQL SERVER 2008

Question

According to cdonner, in his answer here and on his blog.

He claims that BETWEEN with date yields inconsistent results

From his blog:

Answer 1

In Oracle:

select
    case when '1/1/08' between '1/1/08' and '2/1/08'
        then 'in' else 'out' end as s1,
    case when '1/1/08' between '12/31/07' and '1/1/08'
        then 'in' else 'out' end as s2
FROM dual

in out

You are comparing strings here, not dates.

There is nothing BETWEEN 12/31/07 and 1/1/08, as 2 goes after / in ASCII
