By definition, an edge connects two nodes. So clearly, "inject current into a node" is just shorthand for "inject current along a (real or hypothetical) edge leading to a node". This is very common terminology in electronics.

Sure, but wouldn’t it be clearer if they talked about a specific edge? Because there can be several edges leading to a node. (Or, are they talking about, say, all of the “inbound” edges taken together?)

    Thats equivalent according to KCL - I think the equivalent model is "connect a current source I from ground to a node." Thats equivalent to saying "imagine the sum of all currents through edges was -I"
