Promotion applying

Hello.

I have 2 promotions:

1) Entry level which gives 50% off on specified variant (placed price 13$);

2) Order level which gives 1$ off if cart subtotal greater than 10$;

Before applying promotions my cart total is 18$ (subtotal 13$ + handlingtotal 5$).

When I apply entry level promotion I got updated subtotal 6.5$ and total 11.5$. Then I apply the second promotion and I expect that it will not be applied (because condition >10$), but as I see the second promotion is still applied.

I changed the condition to "running total greater than 10$" and now its working as expected but can someone explain whats wrong with conditions built with subtotal/total? And in which cases what conditions better to use? For example, how to change the second promotion to check cart's total (including handling totals and etc)?

Thanks.
