That chart reflects yesterday's positions.
Also note that while I would be very surprised if market makers didn't nudge toward max pain where relevant it is also a kind of self-fulfilling prophecy.
For example, if you buy a call that pushes max pain higher -- but it also induces the market maker to buy the shares (as a hedge) which will push the stock price higher. In a stock like $TSLA where there is reputedly more options trading than usual* then it will have a larger effect than with a stock with less active options trading.
However, it is important to note that the market makers are not perfect. Being a market maker they will naturally have plenty of shares to buy or sell at any given time so they are not likely to actually buy stock for every call sold -- especially if the call is so high they cannot conceive of it being reached. And this is apparently what happened in the run up last fall: the market makers were not sufficiently hedged for the high calls that were sold around, say, May or June because $TSLA had traded around $300 for years and never hit above about $380 so a call at $600 was safe. Until it wasn't -- and they started buying, which pushed the stock price higher, which put more calls into needing hedging, which resulted in more buying...
Anyway, my point is that it is more complicated than a simple max pain number and the market makers sometimes make mistakes.
* reputedly, I've heard this here, but have no information to confirm or deny it
