I don't think so. It doesn't take anywhere near ten turns to get to the transponder.
You've obviously not seen my rolls against the darn imps and piggies...
Anywho, this deterioration of the timer for pre-fight actions could make sense for like an optional thing for Custom Mode and/or built into Honour Mode. But by default it won't make sense. As it's the tutorial area, people who are new to the game will be figuring out the games systems. Maybe they get bad rolls in the fight. Maybe the accidentally knock down some of the caustic pods and create a massive fire they can't get past for several turns. Maybe they get AoO'd by Lord Firesword. Etc.
There's plenty of reasons why a new player might not reach the transponder in 10 turns at which point they're being actively punished for doing what the game promotes... Which is exploring and interacting with things.
It would also set an unreasonable precedent for expecting time to be a factor while playing the game (Which it's not, you can spam long rests to your heart's content and it doesn't impact very much, I think only Nere is actually affected by passage of time from resting)
