From what I can tell, sworded characters (such as guards, mimics etc.) will only trigger their swords to kill whatever occupies the same tile as their sword at the end of their own move.
This means that any character (The player character included) can be pushed onto or through a sword and survive. This can happen if the sworded character themselves is stunned or if the player is using a speed potion to move in between the sworded characters turn or if consecutive pushes are made to bring a character onto and off a sword in the same turn or even if the push is made after the sworded character's turn.
It seems very minor (perhaps even intended as to not mess up priorities) but weird, so I thought I'd report it.
