I have emailed TP to clarify. As this was not what i was told. I have also submitted videos of drivers overtaking me very closely and in some of the videos, I was not on the double yellow lines. I wasn't told it is wrong also.
Cycling abreast is legal.
You missed point #3. As with every other things, T&C applies.
BTW, according to news, he was charged for point #3 in fact...
Cheung was charged with one count of riding his bicycle in a disorderly manner without due regard for the safety of others by riding his bicycle in the middle of the leftmost lane, instead of keeping to the far left edge of the road, hence causing obstructions to faster moving vehicles.
