However, we can't see the bar before it. Could it be there to specifically point out that you release the previous note?
For example, a quater note is commonly held down for quater of the bar, not just played for an 1/8th... So could this be potentially to make the player release for example a whole or half note from the bar before, which gives the rest more pronouciation... if I'm making sense...
I'm just trying to remember years of jazz piano from a long time ago...!
I've never encountered this. If you wanted a note to cut off after 1/8th instead of 1/4 you'd just write the last note of the bar as a quaver and a quaver rest. the notation itself tells you how long to let any note ring for although stylistically I guess people can choose to follow the instruction rigidly or not. If you wanted it really abrupt, mark it as staccato.
A rest in the next bar won't have any impact on the current bar unless it is tied to a rest in the current bar
