Makes sense in a European many-party setting, because while you might gain votes from the centre-right you’ll lose some to the leftist party for the same reason.

Doesn’t apply to a two-party system where there is no leftist party to take votes, the leftists have to vote for the center-left or nobody, and the further away from the right wing party they are the more activated they get by negative partisanship so they will generally vote center-left regardless.
