Why this structure behaves this way
Poor Man's Covered Call is shaped by positive delta and long vega exposure
The deep ITM long call carries a high delta, approximating stock ownership, while the short front-month call caps upside and collects theta. Net vega stays long overall because the long-dated leg retains more vega than the short leg gives up.
