Because it happened to be the first free account in the (raw) directory?
Check:
ls -f /etc/grid-security/gridmapdir | less

If you want to avoid the account from being used, either delete the file
from the gridmapdir (and remove the corresponding DN link) or link it to
some other file that does not cause problems:
cd /etc/grid-security/gridmapdir
ln dteam012 locked-dteam012
When the link count is larger than 1, the account is deemed occupied.
