It is defined that way, because this network is big enough to hold 253 hosts and the 10.x.x.x/8 network is big enough to hold 65535 of those networks. It is commonly used in cooperate networks for a site, and multiple sites are referenced like this: 10.0.0.x <- main site, computing center 10.1.x.x <- remote networks 10.1.1.x <- site a in A 10.1.2.x <- site b in B 10.2.x.x <- RAS networks 10.2.1.x <- dialup accounts on ras server a ... or something like that. this is convinient, but beware network ten.
