I know that they can be combined.

This does not match the documentation.

This says:

   \fontseries{series}
          Select the font series. A series combines a weight and a width. Typically, a font supports only a
          few of the possible combinations. Some common combined series values include:

This implies that \fontseries{series} assigns series to \f@series.
Nowhere does it mention concatenation, or that ‘m’ (alone? others?)
resets it; the only mention of ‘m’ is…

          When forming the series string from the weight and width, drop the m that stands for medium
          weight or medium width, unless both weight and width are m, in which case use just one (‘m’).

… which basically says that, if your combination includes ‘m’ and
other things, you can drop one ‘m’.

I was there earlier! ;-)

The question, all answers and all comments also do *not* mention
that it’s cumulative and reset by ‘m’; they also indicate rather
the contrary (that it’s set to the value given as #1).

>Closing the bug

Respectfully disagree here. At least we have a severe documentation
bug, if not an implementation bug if the documentation is correct
in that it should not accumulate.
