The qualitative conclusion here is that a "wild"
impedance value of 890 - j418 which is far from resonance can and does yield an acceptable
SWR.
I guess there might be a mistake
If Z=890 + j418 Ω then, relative to 50 Ω
ROS=21.7
|S11| = 0.91
S11 = 0.91 -j 0.04
In fact the point you have drawn does indeed produce a ROS < 2 but the impedance it represents is not
890 + j418 Ω or the normalization impedance, which you do not specify, is not 50 Ω
