Font definition in ConTeXt allows extreme degrees of indirection. There
is a lot of flexibility that follows from this. By defining synonyms
such as serif and serifbold and using these in the document, the
document can be written independently of the actual fonts used. The
names are to some degree arbitrary, but used conventionally. There is
nothing stopping you from placing a sans font at the end of a chain of
serif references.
