OK, Janek. Thanks for the tip. I've compiled the files with debug-skylines
set to true and now it's clear that there is a difference. Just take a look
at the at the attachment (the red line was drawn by me).

I've also noticed one more thing: After putting my *.ly file into
LilyPond\usr\bin directory, I've compiled it in two different ways:
- by clicking left_mouse_button twice
- by entering from cmd: lilypond --pdf filename.ly

Using the first method, I got the wrong position of this dynamic mark (too
high), but with the second method, it's position was fine!
