He was able to interact because thats the start of everything and end of everything. Everything happened because of the past, and ends with that. They both saved each other thats why ML could interact with FL. ML saved her at the fire, FL saved him when the wall at the school collapsed (and went back in time)
In order for that to happen both must survive and thats why interacting was possible.
the present you see is like that because everything done in the past is already.. present. like FL is there because one day ML goes back to save her. She can be there because of the past which hasnt happened yet for our ML but will.
