I agree with you that it doesn't make much sense. This may be because as a group, 2+2ers are much less likely to lose the deposit than the average player. Perhaps the sites feel that losing players often stop playing rather than redepositing if they bust out unless they're given an incentive to return. So, while it makes little sense in the case of a decent player, it may be that they're really trying to lure fishy types back to play some more. Once they've deposited, a lot of these folks might play until they bust again, so tying the bonus to a deposit could generate extra play for the site when these folks keep playing beyond the bonus requirement.
