There are still a couple of situations where the USGA and the R&A differ. They don't seem to make them known widely but one that appears on the R&A website is this
Two or More Tees – Connected by a Length of Cord or String
This is a fairly common question and, if considered in the light of the above comments, then you might reasonably assume that such a configuration would be considered non-conforming – as the string could effectively be used to aid alignment. However, this is one of the Rules with an Exception.
In many countries, but particularly in the UK, the use of two or more tees tied together with string has been fairly common for many years – especially in the winter when the ground can be hard due to frost, or when winter mats are in use.
Therefore, within The R&A’s area of jurisdiction (i.e. everywhere except the USA and Mexico) the use of a conforming tee which is connected to one or more other conforming tees by a length of cord or string is permissible – provided the cord or string and other tees are not used to aid the player in his alignment. Such a practice would render the player in breach of Rule 8-2a (Indicating Line of Play).
