What determines #1 and #2 values (with &) for ContourLabels?

Here's the example of a ContourPlot: {i = 0, j = 0}; ContourPlot[{x == 4 + y/4, y == 2 + x/2}, {x, 0, 10}, {y, 0, 10}, ContourLabels -> (Text[#3, {val1[i += 1] = #1, val2[j += 1] = #2}] &)] Print[{val1[1], val2[1], val1[2], val2[2]}] The output is a basic plot with two lines, and I've set it to record and print the values of #1 and #2 arguments, which are: val1[1] = 6.4857 val2[1] = 9.9429 val1[2] = 0.095238 val2[2] = 2.0476 I'd like to know where those values came from so that I can apply the #1 and #2 arguments intelligibly. Thanks in advance.
