ᐅ Are nail trusses only supported in the middle, making them unstable?

Hello dear forum community,

we recently bought an old house and are currently renovating it.

Our carpenter pointed out that he believes there is something wrong with the nail plate trusses, as they seem to rest "only" in the middle and are not connected to each other.

He says the entire structure is subjected to both compression and tension, and the trusses should be continuously connected in the middle. However, he has never seen such a construction before.

It even looks like the trusses were carefully separated afterwards.

In the last photo, you can clearly see that the beam is split in the middle. Although a board was nailed on both the left and right sides, the entire beam is still separated along the center.

I would almost say that someone might have nailed it together improperly and then it was separated again in the end! Unfortunately, we don’t know anyone who is familiar with this type of construction. The question is simply whether this is correct or if we should reinforce the beams in the middle afterwards (they are split in the middle throughout the entire house from front to back).
