Straddling rubber to take signs

Once the pitcher looks in and takes a sign - the runner is getting his full lead based on that. Most base coaches are telling the runner when the pitcher is on or off the rubber. That lets the runner know when to get his full lead.

Bottom line - I'll warn, then call balk.

Is it just me, or is this contradictory? And
what does when the runner gets his lead have to
do with calling a balk?
