question about honeytree mechanics

[paulydoregon]

ok so i recently learned the trick where if you slather a tree after coming across a pokemon, theres a 90% chance the next pokemon to spawn will be from the same list (common,rare, or munclax) as the last pokemon that was on the tree. i was wondering if this trick also works even after the pokemon leaves the tree, or does it only work if you do it after catching/defeat the pokemon from the honeytree? thanks!
