Site Architecture Question on Ties.com - Navigation

[ErikDster]

I'm looking at the navigation structure of Ties.com.  They have various categories like color, pattern, length, brand, etc.

Once you click one of the main categories you get the option to "Narrow Your Choices".

The structure starts like this:

(URL 1) ties.com/black-ties

Then when you narrow your search you get this:

(URL 2) ties.com/animal-print**+**black-ties (notice + sign)

My question: how does Google see URL 2? Is it just like any other link?

[NakulGoyal]

It's just another link. It's completely navigate-able and they have canonical tags in place to prevent any duplicate URLs. It looks good. http://www.ties.com/long+black-ties Canonical is consistent with the linked URL.
