It' s an error in translation/typesetting. In the raws Tadano says something like "But did you... wait for me at the lockers?" and the "After reading Najimi's note" is in the hand-written font, like the one you can see on page 7, meaning it's kinda an extra piece of dialogue. My theory is that someone mistook the hand-written sentence as the main one which resulted in the consfusion.
Hope you understood what I was trying to say
