Looked at this again and seem to come back to my original response.
Could it be that:
The trusses were manufactured for this type of vertical face at the exterior wall? The vertical cord member at that location seems to indicate that.
Is it possible that the owner or whomever, decided to add a continued roof for a covered porch? The extended rafters seem to indicate that.
Was the spacing have been 16" or 20" as was commented? Two foot spacing is standard, except the California spacing of 19 3/16" o.c. spacing. That what those little marks are on you tape rules.
Was the add on 2"x8" rafter splice done properly? NO
Does it void the truss manufactures warranty? NO The truss was not modified.
Was the truss cut off. NO If it had been, you would not be looking at a vertical member at the bearing wall location.
Does this need a Structural Engineers review or recommendation? Only if you want to spend unneccessary monies.
Do you want to recommend further evaluation? Yes A competent local Residential Framing Contractor.
Would more pictures of the outside help? Yes
Hope this helps.
