Have a question for those with experience on reserve. I've been searching through the FSM but can't find a solid answer.

Scenario:

3 day block of reserve. Scheduling assigns you a 3 day trip on day 1 that ends early AM on day 3. Due to delays you don't finish until approx 3am on day 3. Can you be assigned a SCL block 10 hours later on the same calendar day and go fly again?

I was told by a couple guys I've flown with in the past that you can't go back on short call after flying a trip until the next calendar day. I also thought we had a rule about same day assignments, but I'm sitting here with a SCL assignment, even though I already technically flew today (Albeit very early AM). I can't seem to find anything in the FSM about it.
