Changing Product/Category URL_KEY doesn't create a 301 redirect ( EE 1.13)

Question

I'm on EE 1.13.10 and I noticed that changing URL key for a product/category doesn't create a redirect from the previous URL to the new one, instead both URL still works.

Any hint on out to debug/solve the issue ?

UPDATE
-- Example --
I changed URL key from abc123 to 123abc (prod. id:123) and ran a full re-index.

After that:

The link in the frontend are correct but Url_Rewrite table shows following data:

• abc123.html -> catalog/product/view/id/123
• 123abc.html -> catalog/product/view/id/123

So:

1. The redirect from abc123 to 123abc is missed here
2. Both URLs point to the controller (so both links works)

As said above the correct behavior should be that the previous Url redirect to the new one and this is not happening

According to Magento EE Support this the default and expected behavior on 1.13.x
