but why RSUT? I disagree. I think I see what you were thinking based on the horizontal path, but check the vertical.
Because the Plus switches the last two symbols.
-----
Circle - takes off the last letter
Pentagon - takes off the first letter
Diamond - reverses all the letters
Plus - reverses the las two letters.

From the puzzle itself:
QRST -> diamond (reverses - TSRQ) -> Plus (reverses last two - TSQR) -> TSQR
FGHI -> pentagon (takes off 1st - GHI) -> Plus (reverses last two - GIH) -> GIH
So RSTU -> plus (reverses last 2) -> RSUT
The Plus can't swap the last three letters around as I think you're suggesting as the FGHI -> GIH doesn't follow that. If the Plus did swap the last three then it would be IHG.
