Not sure of the reasoning really. But from experience, I prefer looking at short CVs with only useful information in. I'd expect to check references at some point (by which I mean, for HR to) but it's not important information early on.
Here're some results from googling "references available upon request":

In general, you should try to avoid any statements (such as the references one) that are glaringly obvious. Instead, keep a list of references and their respective contact details on-hand in case a prospective employer asks for them. Because this tends to happen late in the interview process and generally only if the company shows an interest in hiring you, there's no need to offer the information in advance.

Seems to me that anyone applying for a professional, salaried position would expect that, after a good enough interview, they would be asked for references. I would not hire someone without at least a nominal reference check, and I would not hire someone who told me they had no references. So why is it so important to explicitly let the interviewer know they have references?
Quote:
Provide reference information when you are asked to provide it. If you reach the interview stage and have not been asked for references, you may offer your reference list.
Generally do not send reference information with your resume unless it has been specifically requested.
They all seem to agree without discussing that references are for later in the process.
