Ambush + moving back in (L5R rules board)

A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from a copy of the forum saved in October 2015, so pages it didn't save are missing. Players' names are left out; the rules officials are named. Rulings are as they stood on these dates; later rulings, the rulebooks and the Rules Archive may differ.

This came up in a game recently:

Daidoji Steve ambushes Isawa John and first action goes to the defender, Isawa John's player plays an action to send home Daidoji Steve (Block Supply Lines for example). Can Daidoji Steve move back in with another action (Doomed Intentions for example) as he was one of the orginal targets of the action and so shouldn't fall under the clause of other units not being allowed to move into the battle?

Relevant text:

Limited: Target one of your unbowed Personalities: Create a battlefield (not at any province). Assign your Personality to attack there. Assign another player’s target Personality to defend there, even if bowed. No other units may move there. Fight a battle there. After it ends, lose 5 Honor.

Thanks
