No, July will still reference to May because it is a 2 month promo.
thats why last time the old birds recommend those new to esaver should just put a bit at start only to test how the system works first.
it is always in 2 month cycle referencing the month before.
so June to July promo will reference to May ADB (In july it will still reference to May ADB).
current promo August to Sept will reference to July ADB (in September it will still reference to July ADB).
then Oct to Nov promo (if continue) will reference to sept ADB
so u empty out on 1st June means your June ADB is 0. but your May ADB is not 0. July will still reference to May and not June. its per 2 months and not purely the month before.
