I just learned this in practice mode the other day.

Im lvl 7 on vlad.

how

i played a lot of morde and there's a lot of bugs that you can learn and discover without even knowing about them

You can also cast ult while charging E as well. It's part of his burst combo. Kind of awkward to do but it's second nature for me now.
