What do you mean by vertical, you mean upside down?
If so, then yes your going to get a lot of oil out, assuming the anti drainback valve in the filter is functioning as it should.
It keeps the filter full so that on start up, the
engine doesn’t have to fill the filter and starve for oil pressure waiting for the filter to fill.
If I had an engine like that, I believe I’d consider a quality
remote oil filter kit that allows among other things to remove a filter without spilling a drop and for prefilling a new filter with oil.
However a trick to help prevent your mess is to have a 1gl ziplock
freezer bag under the filter to catch the mess, a
freezer bag is tougher than a regular ziploc bag.
