Because there is nothing to stop it?

You have to set up trigger on a rising edge and if your comment is correct 
you expect a rising edge every few milliseconds.  Assuming a 9600 bd serial 
port you will only get a couple of characters out in that time so you will 
get several captures for each print cycle each capture higher than the 
other (by about 2200) until the 32bit timer overflows.

Basically it's doing what it's supposed to.
