Excel VBA - Question about Syntax and the Language Structure

To protect and unprotect a sheet you write:
Sheet2.Protect
Sheet2.unProtect

So, how come the same rule doesn't apply to displaying page breaks?  How come you have to write:
Sheet2.displayPageBreaks = True
Sheet2.displayPageBreaks = False

The following would make more sense given the grammar of the protect/unprotect statements.
Sheet2.displayPageBreaks
Sheet2.undisplayPageBreaks

I'm trying really hard to get a philosophical grip on the grammar of VBA and it's quite a chore.  I'm looking for some threads of logic as to when I need to use "=true" or when I need to type a subscript like  worksheets ("sheet1")

OR, do I just need to bite the bullet and memorize these language conjugations.
