how is that possible ?

No it doesn't work quite like that. 
Here's one explaination to look over.
Sync rate is the speed negotiated by your modem and the DSLAM. BellSouth DSLAMs limit the speed to 1472 Kbps downstream and 256 Kbps upstream. This is the theoretical maximum speed possible with FastAccess. The speed that is negotiated is a reflection of line quality and distance. The further away you are from the DSLAM, the weaker the DSL signal, and, at some point, the lower the sync rate. Note that this is a 'theoretical' speed. Your measurable real world speed, or throughput, is always somewhat less than this. Once networking and other intrinsic overheads are taken into account, the maximum real world throughput is about 15-20% less. So that puts the realistic max at about 1200 Kbps, or 150 KB. http://www.gyrene.com/survival/syncrate.htm

To fully understand how telecommunications works would need a trip to the one place with the best explaination and references. It's quite lengthy. http://en.wikipedia.org/wiki/G.DMT
Basically it's a two way street where you rush to the store but take your time to some degree coming back home. Information packets are small bits of data sent to establish your connection to the ISP(internet service provider). Once established small packets are sent by the server to you.
From there when you go to a site the ISP server or servers logs you on by sending small packets out to that site with the slower return. If your ISP is heavily used you remain connected but see an even slower return. That has to do with bandwidth being narrowed. Another factor you have to consider running a test and selecting the server for the test is your location. oh no...

Speedresults key
The red lines are your speed results, placed by download speed within a progression of yellow to dark green lines showing common internet benchmark speeds.
kbps - Speed in thousand bits per second. Modems and DSL lines are sold by their raw kbps speed.
green - Various popular speeds in use on the internet, for comparison
red - How fast your line tested, in terms of data download / upload speed
grey - transmission overhead (assumption 13% for DSL lines, other broadband may have different overhead)
