You thought wrongly, and it's easy to check:

>>> from xml.sax import make_parser
>>> print make_parser(['xmlproc'])
<xml.sax.expatreader.ExpatParser instance at 0x553e56ac>

clearly expat

>>> print make_parser(['xml.sax.drivers.drv_xmlproc'])
<xml.sax.drivers.drv_xmlproc.SAX_XPParser instance at 0x553e590c>

clearly xmlproc

make_parser falls back to its defaults if none of the drivers you list
can be imported.
