BPMN21 — "Flow Object" should be "Flow Node"

The specification says in the (non normative) glossary:

Flow Object - A graphical object that can be connected to or from a Sequence Flow. In a Process, Flow Objects are Events, Activities, and Gateways. In a Choreography, Flow Objects are Events, Choreography Activities, and Gateways.

In the metamodel, the common superclass of Event, Activity, Choreography Activity, and Gateway is FlowNode. Does that mean, Flow Object and Flow Node are synonyms? Or is Flow Object the graphical object and Flow Node the model element? Both words are used throughout the specification, e.g.

Table 7.3 displays the BPMN Flow Objects and shows how these objects can connect to one another through Sequence Flows.

Of the types of Flow Node, only Activities, Gateways, and Events can be the target [of a Sequence Flow].

Does it serve any purpose to have different names for the two? I find it confusing.

Suggestion
Replace all occurrences of "Flow Object" with "Flow Node".
