Welcome to the Home Repair Forums

I will try and help here.

It is possible that what you fear is the cause, You can do some investigating work yourself to help determine the issue. Remove both vents and use a mirror and a flash light to look inside the chimneys for any type of blockage, You would have to look from the top side also because of the bend. You could also jumper out the sensor on one or both furnaces to see if it is the culprit! (I do not recommend running your furnace in such a manner, Jumping out safety's is only for [u]testing purposes only</u>)

As for your venting they are both running metal pipe to the chimneys? The condensation would be from the moist hot air being put off by the furnaces "raining" in your chimney!

"raining" Where the moist hot air from the furnace does not make it to the out side air but instead condensates and rains back down the chimney!

"raining" in the chimney can cause a multitude of problems to include Rotting out the mortar and brick which would cause unsafe erosion to the chimney!
