Does two week rule mean any appointment or investigation?

My partner has seen the GP about blood in her stool. The GP has identified some of her symptoms may be cancer so has made an urgent referral for an endoscopy. I understand there is a two week rule that means they should be investigated within that time frame and it's treated urgently.

However, what she's got is a video appointment to talk to a specialist tomorrow. She has also been given an appointment for a diagnostic endoscopy, but the first appointment is 77 days away in December which is hardly urgent. I can't see how this video appointment is going to be helpful unless she puts the phone up her bum.

We are quite worried because obviously nearly 3 months is a long time to wait to be properly diagnosed. Is the video appointment a tricksy way of meeting targets by saying the patient was seen by a specialist within the time frame? Or will she get an appointment quickly after getting the video appointment? We are considering going private if the wait really will be that long.
