I'm not 100% sure since that's not my setup.
And I'm not sure why you'd want to do that either. My TiVo BOLT has 4 tuners. Each TiVo mini can watch watch live TV using the BOLT's tuners. So, for example, you could watch live TV on the TV attached to the BOLT and three other TVs attached to minis - and still watch a recording on you iPhone/iPad/etc.
Still, if you want to use the Coax cable for multiple uses you should be able to - as long as they are using different frequencies that don't interfere. Here's a article discussing some of these setups and issues:

A lot depends on the specifics of the splitters and filters you use.
