Doubt on randomization method

Sir/mam,
if you run this piece of code in eda play ground (which is randomized for 2 times). so my doubt is when we randomize for 2 times we will be getting 2 random data member values at same 0 second. how my data member can hold those 2 random members(generally a data member cant hold 2 values at current time, if there is a delay then one after other can be hold) at 0 second ?? And how it is received at 2nd component with order at 0 second ??

In reply to subbarao:

Your environment has no time advancement, hence everything runs at time 0.
