Slayer Cutthroat / Ranger Combat Style

[Ornery Hobbit]

Greets,

The Cutthroat needs to burn his 2nd level Slayer talent for Opportune Target. Does this then mean that he cannot opt for a Ranger combat Style down the line, say at 4th level?

Thanks in Advance,

OH

I'm sure he can, RCS for Slayers is just worded like crap.
