it will, unless you blink over walls or enter other parts of dungeon eg . what you reanimate in catacombs lvl 1 won't follow you in catacombs level 2 .
if for example you do an uber with no such situations (k3kba or cows or others as example - open space - ) they will follow all over the map ,
unless you get too far from them , either by running too fast or blinking too far . most of them are moving slow , reason why you are left with the impression that they don't follow - they try to follow , but they can't keep up with your pace , so when you get outside their following range (limited AI), they are left behind
here's a very short example
