Not at all. People on ExTO are considered active pilots, just not flying any schedule. If furlough happens, people are let go in seniority order regardless of their ExTO status. Just look at the seniority list and disregard the "P" letter next to their name. All those outside the furlough currently on ExTO, will stay on ExTO. When the company will need pilots back on the line, they'll have to recall furloughs first before recalling long term ExTOs (at least that's how I understand it).
