Because they arrive over per-packet load balanced ADSLs ( which is done in order to get something at least a bit higher than the line speed for a single flow). Any latency difference between the lines means you're going to get out of order packets so TCP slows down, though it's still something of an improvement compared to single lines. (And yes, in an ideal world there would be enough bandwidth over a single connection to avoid the need to do this, but not always possible for any sane amount of money in rural locations ;)
