Do #2 and #3 indicate different meanings?
Yes, just as your earlier examples 2. and 3. did, though the actual meanings may be ambiguous.
In 3. for example, the adjunct may be interpreted as having a temporal meaning: whilst kicking a stone, John fell into a pool.
Alternatively, and less likely, it may be intended to have a resultative interpretation: as a result of kicking a stone John fell into a pool.
Incidentally, you seem to be drifting off topic.
