Getting longjump stats while getting Cj pre?

Hello. I've been questioned all the time since 2009 when I started playing, mainly because I used it in HNS and I kept it as a habit in KZ. So, basically i have bound Mouse 4 and 5 bind "LEFTARROW" "+left"
bind "RIGHTARROW" "+right" to the arrows of the mouse and before I do a CJ I press the arrow to the direction I'm facing, then perform the normal CJ technique. By doing this, you do a countjump or even a drop bhopjumping and you get LJ stats while perfoming another jump!! and as a result it shows in the screen something like "Script or you use left right key" and people assume it's cheating because, whenever I do it I get 277 or sometimes 278 pre in LJ by doing CJ. And I have hit 258 LJ stats many times by using the built-in cs settings. What do you think of this bug? Has anyone else done it before?
