0 - 2 of 2 tags for rowhash match scan

Hi Folks,
 
I need confirmation on my understaning of Rowhash Match Scan and Sync Scan. 
 
1.
I am joining two tables TableA and TableB using TableA.A1 column which is PI and TableB.B2 column which is not PI.
Prior to join TableB needs to be spooled for Rowhash Match Scan. 

Hi,

is the presence of Rowhash match scan in the explain plan an indicator for Fastpath Merge join?

Thanks
