How to know if an entity is pointing at another?

i am trying to make the conveyor entity things change model when they are merging but it creates issues in the way i am doing it (it will try to connect to others that are not pointing towards it)
execute store result score @s meggtech-var1 positioned ^ ^ ^-1 if entity @n[type=interaction,tag=meggtech-convmarker,distance=..0.5]
execute store result score @s meggtech-var2 positioned ^1 ^ ^ if entity @n[type=interaction,tag=meggtech-convmarker,distance=..0.5]
execute store result score @s meggtech-var3 positioned ^-1 ^ ^ if entity @n[type=interaction,tag=meggtech-convmarker,distance=..0.5]

(could not show the entirety of it but it is checking for the variables and assigning a model to it)
the arrows point to things that i do not want to happen
