It's a safe poke, nothing more really. Got good range for an i13 move though.

Ah, gotcha. I realized that 3K is actually the mid kick you use in stun XD. 6K is still good tho, it reaches pretty far

It's basically a better version of Rig's 6K, which is also 13i, has the same animation , is linear but is unsafe on block. It's a shame Mai's 6K doesn't have any follow-ups, unlike Rig's 6K string.
