At this stage, we are only looking at types of connections made directly to from a boundary Port to part properties of the owning Block (we'll see later that owned properties of a Block may also have Ports if they are typed by a Block that has Ports).
A Connector from a boundary Port to an inner Property - such as from
b1:InnerBlock1 - is of kind delegation,

One of the nicest extensions of SysML over UML is the ability to connect across boundaries to inner Properties of Properties, such as from
nb:NestedBlock across the boundary of
isBehaviorfalse, which just means it does not delegate to the owning block itself:
