Git Submodules and Branches/Tags

gistfile1.txt

According to the Git documentation when using submodules they are recorded at the exact commit they are, but not at symbolic references as master or branch or tag.

Here is a scenario:

1. check out a submodule into master project
2. switch to a specific branch or tag in the submodule
3. add submodule to the master project
4. commit master project

Questions:

1. When someone would check out the master project will he get the submodule version on the branch/tag?
2. If doing a git submodule update will it continue to update from the original branch or will it switch automatically back to master?
