My understanding is that mesayeia is when the person was capable of doing
the aveirah without you. Not "would" but "could". Whereas lifnei iveir
is when the nazir is mei'eivar hanahar and you're giving him passage.

The sugya is on AZ 6a-b.

But, I see the Ran does say mesayeia apply to preventing a nakhri from
violating the 7MBN.

The Rama *YD 151:2) says we are meiqil and allow selling AZ items
to nakhriim if they already own similar items or can buy them elsewhere,
but there are machmirim.

See the Shach YD 151:6-7, who discusses this machloqes rishonim.

Tir'u baTov!
