Not the same. Multiple find requests produce an OR condition. So:
request 1 Name = John will find records with John or those with John in the multiline (no matter where in the multiline).
request 2 Name = Bill will find Bill or Bill in multiline ... etc
Whereas a multiline will only find records with all three names (it produces an AND) condition.
UPDATE: Also if you are searching for a multiline, it will find any multiline records with all three of the names (also regardless of their order in the multiline).
