In context of collaborative work, having names in common for branches would ease communication.
Actual example : I work on the french translation of a project. It has many branches : main, l10n, and others.
main and l10n are managed at different paces by different people : l10n is quickly updated from submitted patches, main slowly integrates updates from l10n.
They use a single mail adress for submit patches.
Of course, locally I work on my own named branch.
