mercurial - What's the difference between "default" and "default-push" in TortoiseHg Settings > Commit? -

in tortoisehg's settings, can set "push after commit" unspecified, default, or default-push. understand unspecified, what's difference between default , default-push?

i did googling, couldn't find explanation.

[paths] default = ssh://hg@example.com/path1 default-push = ssh://hg@example.com/path2 

then

hg pull hg push 

do not refer same repo.
