According to you guys DEL-LHR-LIS-MAD-BCN-MXP-ORD(via LHR) is ok since I only used four segments ie. 1) LHR-LIS 2) LIS-MAD 3)MAD-BCN 4)BCN-MXP. From MXP to ORD (even though it is via LHR) should count as an outward segment and not count in the internal four segments. Am I correct in understanding this?

No. I do not see any through flights from MXP to ORD. You will have to change planes at LHR. That means that MXP-LHR is a fifth segment in Europe. The fact that you are connecting to an intercontinental flight is irrelevant. You will either have to buy an extra segment (assuming you are not originating in Europe) or do one of the other segments you have planned outside the OWE ticket.
Your North American flights look OK as you have only used six segments.
