There is a fixed transmission rate of 23mbps for channel 10. Currently it shares this bit rate between TenHD and TenSD. That's one HD channel and one SD channel.
Channel 1 and channel 12 are not broadcast twice. When you click on either 1 or 12, your TV/Box picks the only HD stream being broadcast. That is to say, channel 1 and 12 are merely 'markers' or 'pointers' to the same HD stream.
With the launch of ONE, Ten has decided to have a simulcast of ONE on a yet to be launched SD channel (probably called ONE SD). This will mean that instead of one SD channel and one HD channel sharing the 23mpbs mux, it will be two SD channels and one HD channel.
The result will be horrible pixelation on the HD channel, and a degredation of the two SD channels. Sports like AFL will be a pixel mess. It defeats the purpose of having a dedicated 24/7 HD channel.
The reason why Ten decided to create a simulcast of ONE was because not everyone has a HD compatible box or TV, so they want people to 'see' ONE even if they can't access channel 1 or 12. It's all about advertising revenue.
