With C-41 films you never completely lose your highlights, you just lose detail. Another reason to overexpose is that apparent grain decreases. These effects work until about three stops over exposed, after that it gets too dark to do much with the negative but get a very flat image. Overexposing increases apparent grain, reduces shadow detail, and increases contrast if you try to fix the thin negative in PS unless you use the multiply layers function. Hope this helps.
