Perhaps, though for RS-232 (now TIA/EIA-232F), the standard was to
use male connectors on DTEs, and female connectors on DCEs.

That might be why.  Or it might be that they were actually following
the RS-232 best practices, since the PC serial port is wired as DTE.

One could even better argue that they should have used some connector
other than a DB25.

Sigh.
