To get four QR segments, you would have to transit DOH twice. (I don't know the oneworld Explorer ticket rules so I cannot say what the transit rules are.)
Very important that you list each segment (even if you're only connecting, rather than stopping over) so that we can assess status earning.
You can transit DOH more than twice. I have 4x DOH transits on my upcoming ticket DFW-DOH-NBO, EBB-DOH-CAI, CAI-DOH-DUB and DUB-DOH-MNL and had 3x on last years ticket (DFW-DOH-TBS, TBS-DOH-CDG, DUB-DOH-CGK).
