If the earth just changed its direction and nothing were destroyed in the process the season would be reversed. The northern hemisphere would have its hot season in December, January and February, not June July and August, as it is now.
If the spin were to reverse and the earths tilt went to the opposite side the seasons would stay the same as they are now Either change by itself would invert the season, adding the second change would invert the inversion.
Think of the football play called the reverse, then think of the play called a double reverse.
