Sorry, I didn’t read it as “in the same step”, I read it as at the same time or as in title simultaneously. 2 steps in a single series for me is “the same time” or simultaneously as the difference is milliseconds.
But to your question of “in the same step”, no it’s not, as can only do create A new thing as in singular thing and of a singular type, there is no action for create new things, as in more than one, and if bubble does release an action like that, it’s probably multiple things of a singular type.
