RE: "include" files

I'm just starting to break out my files and follow a similar philosophy. I have two questions:
1) If I have control sections in my includes, are they all concatenated in order of include?

In other works, if I have:

cfagent.conf
        import:
                cf.blah
                cf.blah2

cf.blah
        actionsequence ( files copy shellcommands )

cf.blah2
        actionsequence ( copy tidy files shellcommands )


will the following action sequence be compiled:
files
copy
shellcommands
copy
tidy
files
shellcommands

?

2) I've been searching for why cfengine has two passes. When I run cfagent, it states that it does
everything in the action sequence twice (pass 1 and pass 2).  I vaguly remember reading about this
somewhere, but I can't remember where.
