Indeed! I missed that. I think you only get one of the eliminations, but it's enough.

Box 9 in my diagram reveals another 5-cell solution in 198, 588, 977, 297 => -198, -297 (in view of cell 91).
Edited later: And of course you could also remove the other Blue equivalents in the box (or elsewhere too for that matter) if there were any need to do so.
