The issue

Bedrock captures context for every iteration of a branching execute command. This differs slightly from Java's behavior.

How to reproduce

Spawn 5 armor stands

/execute as @e at @p run tp @p ~ ~1 ~

Try this in both Java and Bedrock.

In Java, the player is only teleported up one block. The context for the player's position is only captured once.

In Bedrock, the player is teleported up 6 blocks. The context for the player's position was re-captured each iteration.

Java's behavior was reported in MC-125067 and marked "won't fix." I think Bedrock's behavior is somewhat more intuitive, but may be less performant. Regardless, I think it's very important that one behavior is chosen for both platforms.
