how to use two historical fields together

[Eric Cabot]

Say you want to find the tickets assigned to "John Doe" with the status "in progress" in 2018.

If you do this:
status was "in progress" during ("2018/01/01","2018/12/31") and assignee was "John Doe" during ("2018/01/01","2018/12/31") 
you will have a union of both conditions instead of the intersection...

e.g: 

if a ticket was in the following two states in 2018 
assignee="John Doe" and status = "open"
assignee="Jane Doe" and status = "in progress"
but never in the following state
assignee="John Doe" and status="in progress"
it will still be part of the result...

How can we use both historical conditions with a AND type of logic ?
a ticket that at some point in 2018 was assigned to "John Doe" and the status was "in progress" at the exact same time...
