Don't we all just love questions about OBS?

One of the irritating things that my DD's coach teaches is a peculiar way of holding opposing runners on at second base. She has the SS get directly in front (meaning right in line between the R and 3B) of the runner as they come to their stop on their leadoff. The SS is about a foot away from the R. SS trails the R all the way back to 2B, keeping a one foot separation. This brings up a couple of questions in my mind.

Sit 1. As SS is trailing R back to 2B, she gets a little overzealous and bumps in to R. R may or may not show any effects from said bump, and continues back to 2B with no play from the defense. Would this be OBS or is it a HTBT to see the severity of the bump? This actually happened, with no signal from BU, during a game this week.

Sit 2. As BU, you judge that OBS has occured and signal and announce it. However, the R commits a LBR violation subsequent to the OBS and prior to the DB. Are both penalties enforced? This is purely a product of my imagination, but I think you guys are starting to influence me to come up with bizarre, obscure plays that will probably never happen.
