I see that you are using fairly low level commands (plumbing commands)

instead of setting $GIT_DIR/remotes/origin file and using "git fetch".
BTW. "git fetch" will not update branch you are on, unless --update-head-ok
option is used.

instead of 
     git --git-dir=<myrepo> checkout <branch>
(-f is Force a re-read of everything)

--git-dir is alternative to setting GIT_DIR. You can use GIT_INDEX_FILE
to specify alternate index file. Documented in git(7), section
"ENVIRONMENT VARIABLES".
