The density of Misty art - of which there's a fuckload - featuring Sabrina is far less, and is usually because it's an ensemble showing all three of the female Kanto Gym Leaders, or simply all of the Gym Leaders. In all of the official mainline sources, Erika and Sabrina have not interacted. Erika and Jasmine have more in common with each other because of HGSS. Hell, even in Mastersex, Erika and Sabrina don't directly interact. So, what logical rationalisation is left? Occam's Razor: It's because their cities are next to each other.
