I've definitely witnessed this, but I think these are two separate phenomena of "interruption". The COI refers to a case where I interrupt because I understand and I don't require additional elaboration. The way I've often seen women interrupted is more like the interrupter wasn't really listening to the speaker at all and is just arbitrarily taking control of the conversation.
I'd read your point as splitting hairs. In either case, the interruption has happened because of the belief that the speaker is not contributing new, valuable information to the conversation.
On the contrary, I would say that it makes a large difference whether someone interrupts me because they have understood the idea I was trying to communicate, or because they never cared about that idea in the first place.
