GST_ E-Way Bill Requirement

Question is related with E-Way Bill generation....

Assume a Whole Seller Mr. S (located in Delhi) has issued 5 bills having value 40,000/-, including tax, each to different buyers. One Buyer is from Uttar Pradesh and remaining 4 buyers are from same state (i.e. Delhi). Now he loaded all goods related with all 5 bills in his own "commercial" vehicle and want to deliver to all buyers. Now worth of all goods loaded on vehicle is of Rs. 2,00,000/-

Let me know, in this question, whether Mr S is required to generate E-WAY bill for this vehicle movement..

Also quote related statue provision and case laws, plz

Thanks...
