Yes they did.
Glossary - Add the following after the last sentence of On-Going Effect,
“If a duration is not specified, the effect lasts until end of turn.”
so that the entry reads,
On-Going Effect: A ‘continuing’ card effect that is generated by an action. The duration of an on-going effect is set when the action is performed. It may last as little as the duration of another action, or as long as the rest of the game. If a duration is not specified, the effect lasts until end of turn.
So this changes how this char now operates.
