I like G4me4u’s solution, but there are usages for the increased priority of a comparator facing into the side of another comparator too. For example it allows this circuit to have a reliable delay of 2 game ticks, no matter the orientation and redstone update order:

This is a duplicate of MC-54711. I can recommend you G4me4u’s analysis if you want to know how this bug works and how it could be fixed easily.
