I'd hope that this was more obvious...
i = 0
local_size = 0
for po in remote_pkgs:
if os.path.exists(local):
[...]
i += 1
if i == 1 and not local_size and remote_size == po.size:
text = os.path.basename(po.relativepath)
else:
text = '(%s/%s): %s' % (i, len(remote_pkgs),
os.path.basename(po.relativepath))
...here we are walking remote_pkgs, and i is a count of how many pkgs
we've processed. We combine i with len(remote_pkgs) to get the (2/32)
output you see when downloading.

This is pretty magic, you can work it out by downloading and putting
print statements inside the functions (often a good recommendation,
even if only to confirm what you think you know).
What happens is that this line:
result = self.grab.urlgrab(misc.to_utf8(relative), local,
...results in a call to _setupGrab() (via. _getgrab() from the
self.grab property). _setupGrab() uses self.urls, which is another
property setup in _geturls(), which calls _baseurlSetup() this then
gets the mirrors from the mirrorlist or metalink metadata configured
for the repo.
