[Development] Qt wiki MinGW for 64 bit

[niXman]

Hello,

Today, reading this(qt-project.org/wiki/MinGW-64-bit) note, I paid
attention to the fact that it refers to the need to edit qmake.conf
Qt5 for building 64-bit.
But yesterday, I have built Qt5 for 64-bit successfully without
changing qmake.conf.
Tell me please, why in the wiki is said that it is necessary to change
qmake.conf?
