Explained the highlighted part. I dont understand what is going on

A Simplified Example of Validity Evidence Item 1 to 3 Measure X; Item 4 to 5 Measure Y; AV(1-3)=Average of Items 1 to 3; AV(4-6)= Average of Items 4 to 6. Item 1 Item 2 Item 3 AV(1-3) Item 4 Item 5 Item 6 AV(4-6) Item 1 1.00 Item 2 0.65 1.00 Item 3 0.60 0.55 1.00 AV(1-3) 0.70 0.65 0.70 1.00 Item 4 0.20 0.35 0.30 0.25 1.00 Item 5 0.15 0.25 0.20 0.15 0.55 1.00 Item 6 0.25 0.20 0.20 0.20 0.65 0.75 1.00 AV (4-6) 0.20 0.30 0.25 0.25 0.60 0.70 0.65 1.00 Red indicates: Evidence of Reliability and Convergent Validity. (Correlations between AV(1-3) and items 1 to 3 are Item-to-total correlations for X) (Correlations between AV(4-6) and items 4 to 6 are Item-to-total correlations for Y) Green Compare to Red indicates: Evidence of Discriminant Validity. If the above are met: we can then interpret 0.25 as the Estimate of X-Y Correlation
