There are not dormant nubbins along the rhizome for this paste to work.
A typical Cattleya sends out a new lead that is connected back to the previous years growth via the rhizome. The vegetative buds form at the base of a new growth. In Cattleyas there are typically 2 vegetative eyes, quite often 3. Typically there are 2 additional "emergency vegetative eyes" about half size that form about 3/8" or so above the vegetative eyes nearer the rhizome.
There are no other eyes to waken along a rhizome. This is pretty much the story with all sympodial orchids.
