Google stopped direct linking *sometimes* - Why ?

Hi,

Not sure what this means but I thought I share it anyway.

I noticed recently that Google stopped linking directly to sites in it's SERPS. The results always use to have a link like

<a href=http://www.test.com/ onmousedown="return clk(1,this)">

The clk function is used to load an empty image from /URL? with some variables. I guess Google uses this to track clicks on results.
Since a short while, I noticed that the google results for some queries (doesn't seem to be consistant ??) returns links like:

<a href=/url?sa=U&start=1&q=http://www.site.com/&e=xxxx >

To see what I mean try the following links and check out the source code of the page:

http://www.google.com/search?hl=en&i...oogle%20Search

Is different from:

http://www.google.com/search?hl=en&i...oogle%20Search

All I changed in the above is the search query but it returns the links in the 2 different formats as explained above ?? Anyone know why ?
This really baffles me as I assume the 2 queries go to the same server..
