Bizarre behaviour with pcie_aspm=force and iwlwifi L1 ASPM

So I just noticed the following strange behaviour with my Thinkpad X230 and Intel Wireless-N 6205 card. If I boot the system with pcie_aspm=force I get:

#cat /sys/module/pcie_aspm/parameters/policy 
default performance [powersave] 

and

iwlwifi 0000:03:00.0: L1 Disabled - LTR Disabled

If I boot the system without pcie_aspm=force I get

#cat /sys/module/pcie_aspm/parameters/policy 
[default] performance powersave

and

iwlwifi 0000:03:00.0: L1 Enabled - LTR Disabled

Isn't this strange? Does anybody have an explanation?
