It's an insider leak. He can't post pictures, but he can post cartoons, and unusually detailed ones at that. It's reasonable for the J-10 to move to TVC; if thrust is significantly increased to 140+ kN, then CFTs to extend aircraft range on the PLAAF's mass striker aircraft become viable. But while thrust increases can compensate for acceleration losses, they can't compensate for agility losses, which is where TVC comes in. Then the PLAAF has a high-low combination of Chengdu J-10s and J-20s; the former being used to strike and provide clean-up fire, while the latter is used for air superiority and anti-radar roles.
You forget to mention the wingtip hard points....
