Not to pick nits, but it's actually the reference oscillator, supplying the signal against which the (demodulated) subcarrier (i.e., chroma signal) is referenced.
All the while, the burst signal, coming as as quick "burst" during retrace, locks the reference osc. to a steady 3.58 Mhz. The burst is only a small number of cycles in duration. Then the osc. simply "coasts" on thru the scan period.
The tint (or hue or whatever) generally works by varying the phase of the burst signal.
(Edit.) GE's "ringing tank" is a shortcut method of achieving the same result minus the dedicated reference oscillator.
