It's not much different than the old Allardyce style at Blackburn is it? His players used to make a point of arriving fractionally late and making enough contact to knock people off balance, but play would continue. Spurs' pressing is more aggressive than Liverpool/City, so they make more contact. Fouls may be given, but they're not often bookable offences, and more often play will continue as there's apparently an advantage to do so.
There are obviously some glaring instances - the WHU fullback that's been mentioned, Rooney in the derby - but the number of cards/foul is only important if those decisions are wrong. Most of City's bookings that I've seen have looked fair enough to me; Marriner was lenient, but lenient to both sides.
