Pay levels are not compared here: each role's figures come from different countries and currencies. They are on each role's own page. Pay disclosure tracks local pay-transparency law more closely than employer policy, so the two rates partly reflect where each role is advertised.
This compares what employers ask for in the two roles; it does not count how many people hold those skills or say that one role can do the other.
