No, that's documented behavior:
```
Multiple target back ends implement the target attribute to specify that a
function is to be compiled with different target options than specified on the
command line. One or more strings can be provided as arguments. Each string
consists of one or more comma-separated suffixes to the -m prefix jointly
forming the name of a machine-dependent option. See Machine-Dependent Options.
```
It allows you to specify multiple target options.
