Going back to Sensor Net Activation, it might be helpful to think of it like this logically:
Paid: Spend hosted power counter to
Effect 1: Rez a bioroid
Effect 2: Conditional: Derez that bioroid when turn ends.
The important distinction is that, even though it is a conditional ability on the turn ending, it is nested within the paid ability, and thus exists after the paid ability has fired, regardless of if the card itself sticks around (because abilities exist independent of their source once resolved).
This is a different case than abilities with a line break, that are disjoint. For example, using the same notation for breaking news would be:
Conditional: When you score breaking news, give the runner two tags.
Conditional: When your turn ends, the runner loses two tags.
Note that one ability isn't nesting the other (because they are on separate lines), and thus both are dependent on the source (being the card, Breaking News, in this case). If the source goes, the ability goes.
