Thanks, but unfortunately not. I guess, I simplified the MWE too much.
This does not align the b and c. It should become clear here:

```
\startformula
a               = \alignhere (b, thisislonger) \quad \text{with}
                   \breakhere b = \text{something}
                   \breakhere thisislonger = \text{someother}
                   \breakhere
\text{somelong} = \alignhere bla
\stopformula
```
