Composition gst applicability

A dealer has done business for less than 15 lakhs during FY 2016-17

and for period April 2017 to July 2017 has raised interstate bills and service bills for value 4 lakhs during the 4 month period in total.

He has opted for Composition scheme under GST and has decided to do only Local business in Goods and NOT do any interstate or service business after start of GST - 

Now question is - Is he right to opt for composition scheme ?

Since he has done interstate business before GST introduction and service bills too - does it in anyway disqualify his business for composition ?
