I agree. However it seems to be the correct behavior. Please read #2 to 
find the way to fix it.

If you use Nagios3, you should use "inheritance":

You should create 2 hostescalation/serviceescalation, each of them 
having different escalation_options.

Notifications seem to be triggered when Nagios is receiving new results 
from the "check result reaper" for the specific host. Nagios won't 
escalate the problem by itself if there's no new results.

Although this FAQ entry does not specify it explicitly, the same logic 
applies for your case:
