No, this says nothing about the relationship between Russia and China. This says everything about the relationship between the SWIFT system and Chinese banks. Russia will get paid. China just can’t risk being locked out of SWIFT.

Stocks Tied To China’s SWIFT Alternative Are Soaring
Therefore China has other ways of trading with Russia. They could become the gatekeeper for Russian trading.
Also in a related note fertilizer production may be gravely impacted:
Russia is #4 in nitrogen and phosphate based fertilizer:

Russia is #1 producer of NPK and urea based fertilizer:

So by blocking the ability to pay for Russian goods, you not only have oil and natural gas shortages (which means shortages of all sorts of industrial chemicals used in medicine, plastics, etc.) but you also have shortages of food as we will knock out a huge supplier of the world’s fertilizer.
Without food, that means fewer people. Maybe that is the intention.
