It is an enormous change to the whole strategy.
In most gomoku variants overline is treated as null (in renju for black as a loss), only exactly 5 is a win. Allowing for overlines leads to a duller version suitable for beginners.

There is a distinct difficulty for most computer gomoku engines not to fall prey to a skilled human player who detects that the computer is bound to get an 'overline' (6 or 7, with an impossibility to end up with exactly 5) and nonchalantly build their own combination and the computer player loses immediately.
