git sync reset --hard?

[dalehhirt]

My definition of sync is

• Pull latest commits
• Push latest commits

Why does it also do a hard reset?

[spacewander]

To ensure all the states are synced (not just the commits).

So that spawns 3 more questions:

1. Why does the "soft" reset as well? Shouldn't it only do a fetch, and not a reset?
2. Why do neither do a push? A sync would seem to indicate that we send our commits up as well as pull down?
3. why not stash any current changes as to avoid a merge conflict?

The script is written 5 years ago. I know its purpose, but I can't recall why the author chose A but not B.
