I haven't followed this thread at all but this is a common feature on
many laptops. There is often a BIOS setting for it. I didn't find the
manual for the P72 in a quick search but the P71 manual turned up this
BIOS option:
Wireless Auto Disconnection
Values: Disabled, Enabled
Descriptions: Enable or disable the wireless automatic disconnection
function. This is selectable only when an Ethernet cable is connected
to the Ethernet connector on your computer. If you select Enabled,
Wireless LAN signals are automatically turned off whenever an Ethernet
cable is attached

Many of my friends, my father, my siblings, and I have all worked for
various government agencies or contractors (for one of this group,
all the Lenovo laptops were confiscated by IT). WiFi was not
permitted in many government workplaces, and you were not allowed to
connect a switch or router to the one LAN port in your
office/cubicle. Some people got around this by running AP's on
their laptops, so it would not surprise me that a Lenovo laptop
marketed to governments would have firmware that does not allow
simultaneous use of ethernet and wifi. I once attempted to purchase
a couple Lenovo laptops, but was told I had to work with Lenovo's
government sales office. I was told they normally deal in purchases
quantities in the many 1000's, but always had a few extras built so
if I could wait until an order was complete I might be able to get
one of the extra systems. I assume those extras end up being sold
in irregular channels.
