Might be that part of the squad was standing closer to the area you commanded them to throw it than the rest of the squad.
But yeah if it were to stick it should have satchel range. Wasn't aware it had 2 more range.
i don't know what is going on but i tried with cheat mode, i pretty much ordered a squad to throw the nade, and they moved until it was in range to throw it, then did the same but this time i just ordered them to use it a few meter more, and they didn't move and just ignored the circle cause 1 part was still inside, just copy paste the satchel range and all should be OK (so the minimum range is removed too)
