• 1. Create a scoreboard objective called "Test"

     /scoreboard objectives add Test dummy
     

  2. Set it to display sidebar

     /scoreboard objectives setdisplay sidebar Test
     

  3. Set score of fake player Notch for Test to 1

     /scoreboard players set Notch Test 1
     

  4. Set your score for Test to 2

     /scoreboard players set @p Test 2
     

  5. Perform this command:

     /scoreboard players operation Notch Test > @p Test
     

This will set Notch's score of Test to 2, BUT the question is why:
Because Notch's score of Test is smaller than yours so it is incorrect which should NOT cause to set Notch's score to your score.

Probably they just messed up "<" and ">"
