If you refer ASME B31.1, it covers only boiler external piping (BEP) as illustrated in fig 100.1.2(A), (B), (C)
The dark line indicates BEP (scope under B31.1), including terminal points. The terminal points are defined else where in the code (refer para 100.1.2)
In my opinion it is designers responsibility to Cleary define the terminal points on the drawing, to avoid such confusion at construction sites
