Why would multi-power-pass splitters exist if that were the case?

<div><br>It can be an issue if one device wants horizontal and one wants
vertical - horizontal will be the polarity chosen. That's what happens now
with Sky on V and Freeview on H (though it seems to me that it's still better
have Freeview with the potential to screw up a simultaneous Sky recording than
to not have Freeview). But once Sky switch to H on Tuesday morning both will
be the same anyway so it would only be an issue if you were using some
vertical polarity DVB channel ( i.e. non-Freeview). AFAIK it shouldn't be a
