Hmm. Now would that be the Accord or Prelude manual. Wait, I own both the factory manuals and almost have them memorized as I've had this swap for over a year now!
Of course tension is driven by the tensioner. When I swapped out the lousey Prelude tensioner for the H23, I had this in mind.
Torque on the exhaust pulley creates slack in the front part of the belt, allowing stuff more easily to be accomplished with the flywheel gear. Conversely, reverse torque on the intake pulley frees up slack in the back. A combo of these allowes the thoughtful user to more easily get the timing belt on and on correctly. No mean feat when things are extra tight due to above tensioner mod and the fact that 3 critical alignments are being done.
I'd be much abliged if someone still has the writeup or the link. Otherwise, please just move along, nothing to see here.
Tks,
Bob
