There is no reason to rename invite to squad to invite to group. It is even more confusing than changing the icon for collision compensator module every few patches.
Squad is also much better name/definition for players playing together than group. Group doesn’t have by definition anything to do with a few people working/flying together.

Group is used in military but only for much larger force and not for a few guys fighting together:
