This is correct, except it's 186cm for keepers, not 185cm
This means that generally aerial ability will/should be 2-3 points lower than jumping, assuming the length of the keepers' arms are average.
It is indeed very confusing and the 2-3 point difference is not properly implemented in the database (check out Kasper Schmeichel, Alisson, Ederson, etc.) which underlines that it's difficult to grasp. Not sure how these numbers are set for newgens.
