Most people in the ASD community don't put much stock in different "types" of ASD anymore, because there isn't really a lot of evidence that said subtypes are meaningful and people can move between them throughout their lifespan. (What the person in the transcript says about autistic subtypes is not accurate; ASD-1 is not the same as the old Asperger's diagnosis.)
I agree with the person in the transcript that PDA is an overpathologizing and prejudicial name for this profile, and that describing it as masked autism is more accurate. (The DSM-5 allows for autism to be diagnosed in masked cases, actually: it says that the symptoms can be masked by learned strategies.)
Here's a description of what masking autism is like by someone in the community.
