"execute as" not working with teleport

I expect @e[tag=destination] to teleport relative to itself. When running the following and both buttons exist I expect @e[tag=destination] to move 3072 block. It only moves 2048 blocks.

execute positioned as @a[tag=crouched] if block ~-1 ~1 ~5 minecraft:stone_button run teleport @e[tag=destination] ~ ~ ~1024
execute positioned as @a[tag=crouched] if block ~1 ~1 ~5 minecraft:stone_button run teleport @e[tag=destination] ~ ~ ~2048

Thank you! Your edit worked as desired.
