Yes. Xunlei broadens the capacity of uploading servers. But I think the reason is NOT as you described, "the files are presented on ADSL or modem machines".
As we know, those websites providing download services usually limit the number of simultaneous downloading threads from a single IP address (or client), so that they can serve more users concurrently and avoid malicious attacks. As a result, the speed of a user downloading a file from a single server is constrained. Xunlei provides multiple servers to a user, thus improving the parallelitiy. On the other hand, I think P2P content sharing is helpful to accelerate the downloading process. But I am not sure whether it's practically enabled in Xunlei.

Assuming they're all servers with public IP addresses and reasonable outbound bandwidth, having each client load-balanced to a single specific server and downloading over a single TCP stream is more efficient for the network -- and provides better download performance for the user -- than having multiple TCP streams fight over the same congestion-limited download pipe. The only reason to download from multiple sources simultaneously is the case where upstream capacity of serving nodes is a small fraction of downstream capacity (see: P2P filesharing network where the files are only present on ADSL or cable modem connected user machines), and thus there'd be no way to fill the download pipe otherwise.
