Removing product from cart block does not seem to trigger event 'After removing a product from the cart' in rules

When removing a product from cart using the Ajax Block in this module it does not seem to trigger the event 'After removing a product from the cart' in rules.

I have noticed this when using Commerce Coupon module and creating a minimum order total requirement for a coupon to be redeemable using rules.

In this situation there needs to be a way to stop a user from adding a coupon when their order total is above the minimal order total required for that coupon, and then removing a product and continuing to checkout, as their order total is now below the minimal order amount, yet the coupon is still active.

I have created a simple Rule to deal with this issue which is as follows

EVENT
After removing a product from the cart

ACTION
Remove all coupons from an order

This does not work when removing an item from the cart (unless doing so on /cart page)
