Why here is used FirstPageBitmap.Scanline[FirstPageHeight-1] and not FirstPageBitmap.Scanline[0]?

It hard to tell for sure without knowing how FirstPageBitmap is defined. I've never used Delphi so here's my best guess: the Scanline member is an array of pointers into one large buffer (the image). Since that buffer stores the image bottom up (as the message you quoted says), the pointer of the last scanline actually points to the start of the buffer.
