Why "to include" and "to implement" wron

[goelmohit2002]

Hi All,

In one of the very popular Notes freely available on the net(Sahil ones)...i read the following rule. Can someone please help me understand what is the reasoning behind the same ? Is it really the case that is followed in GMAT world or not ?

Infinitives to Avoid
“To include” is usually incorrect,
while “including” is more often correct.
“To implement” is usually incorrect,
while “implementing” is more often correct

Thanks
Mohit
