The first acoustic guitar goes like this...

e----------------|
B----------------|
G----------0-----|  Repeat.
D-----0--4--4p0--| 
A----------------|
E---3------------|

When the second acoustic guitar comes in, it's played at the same time as the first guitar. 
Again, listen to the song for timing. It goes like this...

e--------------------|
B--------------------|
G---4-0---0--0-------| Repeat.  
D-------4--4---------| 
A--------------------|
E--------------------|

Then it slows down a lot and then it ends on....

First guitar
e--------------------|
B--------------------|
G--------------------| 
D--------------------| 
A--------------------|
E---3----------------|

Second guitar
e--------------------|
B--------------------|
G---4----------------| 
D--------------------| 
A--------------------|
E--------------------|

I hope this made sense. 

God bless!
