How it could "decode" incorrect image and display as a demo in various articles? I do not believe that video codecs are able to decode over "encrypted" data and produce some video stream.

the point of insertable streams is that you can hook into the compressed payloads and encrypt them after compression, and then decrypt them before decompression. The codec never sees encrypted data.
