Narrative:
Location: ord. On taxi out, lmfdu message of wing anti-ice. Per checklist, we shut off #1 bleed and APU bleed. Warning cleared. First officer and jump seat rider suggested we return to gate. Since the warning didn't appear after going bleeds back on, I elected to continue with the flight. After airborne, I discovered that the checklist required a return to gate with this warning even if it had cleared. My mistake -- since I didn't read checklist properly. Supplemental information from acn 536709: in addition, the taxi and procedure were interrupted trying to obtain contaminated runway data. En route after things had calmed down the captain read the checklist procedure and stated that he misinterped the return to gate instruction.
