The straight parry of Italian rapier is designed primarily to defend against the straight thrust. So what would happen if you instead threw a series of tip cuts to the face? Since they will be coming from odd angles they may evade the parry entirely. And if blocked incorrectly they quickly become a thrust.
Their is an element of danger. The preparation for the cut leaves you vulnerable and thus must the done at the widest possible measure. And even then the shorter range of the cut means a long thrust might come in.
The forward stances of Meyer will reduce the danger because they obscure the true range. Opponents will need longer thrusts to reach the body while your own sword is quite forward. Therefore mastery of them is a prerequisite.
