Resequencing a BHAV with unused lines

The next BHAV discussed in the SimsCollege lesson is BHAV 4112 CT - sit comfort, and it starts out like this:

Although the SimsCollege lesson for IFFPencil 2 suggests rewriting the BHAV, it is not a good idea to let IFFSnooper resequence it just yet...

This is because the function outcomes for the very first line are both FE (return true). The other lines are therefore ignored by the game.
If you resequence a BHAV with extra unused lines, IFFSnooper will delete them, so BHAV 4112 ends up looking like this:

Don't worry about throwing away some potentially important information when you resequence a BHAV. The resequenced BHAV is not substituted for the original unless you close the resource window by clicking on the "OK" button.
