Insert mesh brush - Problem

Hi
Maybe someone can explain what I am doing wrong. Or is it just as it is?
I create a new insert mesh brush. Use the stroke brush with lazy mouse aktiv and lazy step. When I do a stroke on a tool always the first inserted mesh points to a wrong direction. Why? See screenshot. I use the brush with lazy mouse instead of curve stroke because they let me make the placement of the insert meshes more uneven and wobbly.
