Before being Stilled Siuan was clearly stronger. Now she and Leane are pretty much equal in Power. If they had lost a set value from the Healing they would have maintained the same Power difference.
If you do the math (Siuan staring at 50 and Leanne at 45) they end up as a 16 and a 15 (very weak AS), which works cleaning if they each lost 2/3 of their strength yet wind up very close to each other.
I think a fixed % is far more likely in this case, for the very reason you state! The conduit needs the opposite source to be 100% effective.

I think I worked out that they lost 15 strength once, though I used 10 in the examples above with Fionwe.
Siuan : 25 - 15 = 10
Leane : 24 - 15 = 9
That essentially makes them a third as strong as they used to be. There's no proof that they're equal. Leane directly says that she's weaker than she was, and so is Siuan, though both were once very close in strength.
Of course, I'm scandalized that you think that Siuan has a strength of 50 - as if two of her could match Rand al'Thor. Perhaps this is for that other thread though

I think that since Moiraine was in another dimension, the Bond passed to the closest holder.

The only possibility is "something weird" if Cyndane ISN'T just "Lanfear"

Maybe they put some of Ilyena in Cyndane.

Right, But Ilyena Doesn't Need Lanfear for That Either.

Moiraine will make a huge difference to TG (Min's viewing) so I think she will need to channel. *NM*
