Call of Duty Modern Warfare 2 Strafe Glitch

starts at 0:17 s ... ... sick jump across map @ 0:45 s
nothing crazy, just wanted to upload it to show a couple friends that cant just come over and see it.
What's happening? Basically forwards/backwards is normal, but side to side (strafing) is crazy fast. Wanted to document it before it got fixed...
