Imagine this scenario.
You're diving along a line that has no arrows whatsoever, other than jump arrows (if any). At one point you come across a back to back arrow, indicating there is now a closer exit ahead.
So lets assume that 150' after that you place a jump with an arrow pointing to that new exit, an exit that you have never actually seen and verified.
The next thing is an unsuspecting diver who, for some reason or the other, gets onto your jump line from other side (towards the main entrance), for example through a side passage. This diver now sees your jump and the arrow, pointing to the new exit. The diver may know nothing about the opposing back to back arrows and the directional change, believing this is his exit.
Good luck if he is in backmount, is stupid enough to trust the arrow and the exit goes through a SM restriction.
So maybe the solution is, drop an arrow (if so preferred) only when the nearest exit matches your exit. In case the nearest exit is not yours and/or unverified, tie into a cookie instead of an arrow and use a second cookie (or better still a clothespin) to mark your exit side.
