To know the last record, you have read the full input stream and then in the END pattern, print out the records. Since you are using an associative array in the mentioned manner, the elements of it will always contain the last records of any group.
And, setting OFS is useless in this case.
Code:
BEGIN{FS=";"}
{array[$1,$2]=$0}
END{for(a in array) print array[a]}

GIT-SYMBOLIC-REF(1)						    Git Manual						       GIT-SYMBOLIC-REF(1)

NAME
git-symbolic-ref - Read and modify symbolic refs SYNOPSIS
git symbolic-ref [-m <reason>] <name> <ref> git symbolic-ref [-q] [--short] <name> DESCRIPTION
Given one argument, reads which branch head the given symbolic ref refers to and outputs its path, relative to the .git/ directory. Typically you would give HEAD as the <name> argument to see which branch your working tree is on. Given two arguments, creates or updates a symbolic ref <name> to point at the given branch <ref>. A symbolic ref is a regular file that stores a string that begins with ref: refs/. For example, your .git/HEAD is a regular file whose contents is ref: refs/heads/master. OPTIONS
-q, --quiet Do not issue an error message if the <name> is not a symbolic ref but a detached HEAD; instead exit with non-zero status silently. --short When showing the value of <name> as a symbolic ref, try to shorten the value, e.g. from refs/heads/master to master. -m Update the reflog for <name> with <reason>. This is valid only when creating or updating a symbolic ref. NOTES
In the past, .git/HEAD was a symbolic link pointing at refs/heads/master. When we wanted to switch to another branch, we did ln -sf refs/heads/newbranch .git/HEAD, and when we wanted to find out which branch we are on, we did readlink .git/HEAD. But symbolic links are not entirely portable, so they are now deprecated and symbolic refs (as described above) are used by default. git symbolic-ref will exit with status 0 if the contents of the symbolic ref were printed correctly, with status 1 if the requested name is not a symbolic ref, or 128 if another error occurs.
