So far your assumptions seem fine, but... how long is this pole? The reason I ask is that it looks more like a reaching strut than a whisker pole with that outboard end. If it's just 3 or 4 feet long that's what it may be.
Typically a whisker pole is telescoping and has a pin at one end to insert into the clew cringle. Also a pole lift generally is not required when using a whisker pole, the jib leech will support it.
If you have spinnaker gear (sounds like you do) and the pole is shortish then it's not a whisker pole.... As a reaching strut the outboard end will extend just outside the lifelines at 90 deg to the mast. It's purpose would be to keep the guy from chafeing on the shrouds during a tight reach.
