Yes it is reserved swap.
The swap space that is really written to swap devices is shown with
Code:
swap -l

This looks like top output. I wouldn't recommend using it to investigate memory usage. You'd rather use native tools to figure out how much physical, virtual and swap memory is used on you system.

Please post the output of these commands:
Code:
swap -s
swap -l
vmstat 2 2
echo ::memstat | mdb -k 
prstat -Zc -n 1,100 1 1

My question(s): If I have available RAM, why am I using swap?
There is no evidence you use or not swap from top output, but there are certainly situations where it is legitimate for swap to be used while plenty of RAM is free. You can even have applications crashing with an out of memory error while plenty of RAM is available.
